-// Package cmp determines equality of values.
-//
-// This package is intended to be a more powerful and safer alternative to
-// reflect.DeepEqual for comparing whether two values are semantically equal.
-//
-// The primary features of cmp are:
-//
-// • When the default behavior of equality does not suit the needs of the test,
-// custom equality functions can override the equality operation.
-// For example, an equality function may report floats as equal so long as they
-// are within some tolerance of each other.
-//
-// • Types that have an Equal method may use that method to determine equality.
-// This allows package authors to determine the equality operation for the types
-// that they define.
-//
-// • If no custom equality functions are used and no Equal method is defined,
-// equality is determined by recursively comparing the primitive kinds on both
-// values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported
-// fields are not compared by default; they result in panics unless suppressed
-// by using an Ignore option (see cmpopts.IgnoreUnexported) or explicitly
-// compared using the Exporter option.

-// Equal reports whether x and y are equal by recursively applying the
-// following rules in the given order to x and y and all of their sub-values:
-//
-// • Let S be the set of all Ignore, Transformer, and Comparer options that
-// remain after applying all path filters, value filters, and type filters.
-// If at least one Ignore exists in S, then the comparison is ignored.
-// If the number of Transformer and Comparer options in S is greater than one,
-// then Equal panics because it is ambiguous which option to use.
-// If S contains a single Transformer, then use that to transform the current
-// values and recursively call Equal on the output values.
-// If S contains a single Comparer, then use that to compare the current values.
-// Otherwise, evaluation proceeds to the next rule.
-//
-// • If the values have an Equal method of the form "(T) Equal(T) bool" or
-// "(T) Equal(I) bool" where T is assignable to I, then use the result of
-// x.Equal(y) even if x or y is nil. Otherwise, no such method exists and
-// evaluation proceeds to the next rule.
-//
-// • Lastly, try to compare x and y based on their basic kinds.
-// Simple kinds like booleans, integers, floats, complex numbers, strings, and
-// channels are compared using the equivalent of the == operator in Go.
-// Functions are only equal if they are both nil, otherwise they are unequal.
-//
-// Structs are equal if recursively calling Equal on all fields report equal.
-// If a struct contains unexported fields, Equal panics unless an Ignore option
-// (e.g., cmpopts.IgnoreUnexported) ignores that field or the Exporter option
-// explicitly permits comparing the unexported field.
-//
-// Slices are equal if they are both nil or both non-nil, where recursively
-// calling Equal on all non-ignored slice or array elements report equal.
-// Empty non-nil slices and nil slices are not equal; to equate empty slices,
-// consider using cmpopts.EquateEmpty.
-//
-// Maps are equal if they are both nil or both non-nil, where recursively
-// calling Equal on all non-ignored map entries report equal.
-// Map keys are equal according to the == operator.
-// To use custom comparisons for map keys, consider using cmpopts.SortMaps.
-// Empty non-nil maps and nil maps are not equal; to equate empty maps,
-// consider using cmpopts.EquateEmpty.
-//
-// Pointers and interfaces are equal if they are both nil or both non-nil,
-// where they have the same underlying concrete type and recursively
-// calling Equal on the underlying values reports equal.
-//
-// Before recursing into a pointer, slice element, or map, the current path
-// is checked to detect whether the address has already been visited.
-// If there is a cycle, then the pointed at values are considered equal
-// only if both addresses were previously visited in the same path step.

-	//	• Searching for differences switches back-and-forth between
-	//	a search that starts at the beginning (the top-left corner), and
-	//	a search that starts at the end (the bottom-right corner). The goal of
-	//	the search is connect with the search from the opposite corner.
-	//	• As we search, we build a path in a greedy manner, where the first
-	//	match seen is added to the path (this is sub-optimal, but provides a
-	//	decent result in practice). When matches are found, we try the next pair
-	//	of symbols in the lists and follow all matches as far as possible.
-	//	• When searching for matches, we search along a diagonal going through
-	//	through the "frontier" point. If no matches are found, we advance the
-	//	frontier towards the opposite corner.
-	//	• This algorithm terminates when either the X coordinates or the
-	//	Y coordinates of the forward and reverse frontier points ever intersect.
-	//
-	// This algorithm is correct even if searching only in the forward direction
-	// or in the reverse direction. We do both because it is commonly observed
-	// that two lists commonly differ because elements were added to the front
-	// or end of the other list.

-//

-// should be considered equal. The definition of equality chosen by Equal
-// requires two graphs to have the same structure. To determine this, both the
-// x and y values must have a cycle where the previous pointers were also
-// encountered together as a pair.
-//
-// Semantically, this is equivalent to augmenting Indirect, SliceIndex, and
-// MapIndex with pointer information for the x and y values.
-// Suppose px and py are two pointers to compare, we then search the
-// Path for whether px was ever encountered in the Path history of x, and
-// similarly so with py. If either side has a cycle, the comparison is only
-// equal if both px and py have a cycle resulting from the same PathStep.
