Prosper is a Forth-like stack-based language. While taking specific influence from Forth, it does not attempt to emulate or implement the ANS Forth standards.
Currently, the language is entirely interactive -- to explore, simply run `go run .` in the root of this project and an interactive session will begin.
## Syntax
Prosper is stack-based, as mentioned, so all the standard stack semantics are present:
* Rearchitect how compilation works -- currently, non-built-in words are stored as raw sets of strings, which means in the case of things like IF/ELSE/THEN we have to re-parse the tree and use the IFStack to track the parse status. It'd be better to compile to some intermediate representation so that the compiler can store the JMP locations inline and execution just flows from instruction to instruction instead of re-parsing the entire descent-tree every time.
* More looping constructs (`EXIT`, `?DO`, and `WHILE` would be nice).
* Add ways for Prosper words to hook into the input/output streams (probably required for self-hosting a prosper compiler in prosper, which is a long way off).
