RPNFL (Reverse Polish Notation Functional programming Language; Working Title)

This is a project to design and implement a functional programming language which incorporates some ideas I have about how functional programming could be done differently.

The core ideas are:

• The language has no keywords as part of it's syntax. All program structure is represented with symbols. Only variables/functions/types/etc., are alphanumeric.
• The arguments to a function come before the function, not after it (e.g. we write x y f instead of f x y or f(x, y) or (f x y))
• A function can be "unordered", meaning that it's arguments can be given in any order (e.g. for a function f:a->b->c with a != b, x y f and y x f are equivalent; With this we can also curry on any argument: x f:b->c / y f:a->c)
