An experiment: A small (unfinished!) JIT-compiled (x86) functional language -- just to see how small it can be.
And I'm sure this can remain under 1k lines and still be a real/usable language -- but for now it's just a glorified calculator with extra features. ^^ See struct TestS (in flak.cc) for built in tests that demonstrate most of what is supported at this stage.
The makefile just invokes ./build; and build assumes clang++ is present. Edit as needed. :)
If you make improvements, please share; that would be kind. :) BSD license, as per flak.h and LICENSE.
