Untitled Programming Language (UPL)

This is a toy programming language.

All operators are infix and right-to-left associative. For operators that only use the value on one side, it is convenient to use one of the single-character operators as a filler (ex ,)

,print "Hello World!\n";

For more example code, see the examples directory.

See builtins_load_all in builtins.c for the list of builtins.
