Wrapping an if in a lambda is unlikely to work as expected.

  ((if foo + -) 4 6) Can be compiled to (function() if foo then return plus else return minus end end)()(4, 6) It is far too verbose to be used in manually crafted Lua, but acceptable if you treat it as a compiler target (with the caveat that the lambda creation will prevent LuaJIT from JITting that piece of code).

    Plug https://github.com/meric/l2l https://github.com/meric/l2l "A object-oriented, unicode-enabled lisp that compiles to and runs as fast as Lua. Equipped with macros and compile-time compiler manipulation. Comes with all built-in Lua functions."

      Nice one! I started coding one after writing the above comment. I have a question regarding your implementation: why do you use `goto`s rather than `elseif` to compile `(cond)` blocks? For nested blocks?

        Oh I think it it was for the return value of cond.
