Right, so I think the suggestion of brainfuck illustrates the difficulty I’m having articulating what I want, because while it’s TC and trivial to implement, it is basically impossible to use as a language. I think I’m going for simultaneous ease-of-implementation and ease-of-use rather than any actually type of “minimalism”.
I’m probably just looking for Lisp, really. It’s easy to implement and usable enough.
Yeah, a simple Lisp like Scheme is basically the lambda calculus.
Brainfuck is useless because the operations are useless. But if you give the user a few more things, like addressing memory, basic arithmetic and a way to define variables and functions, then you have something way more useful very quickly.
