> If only it had macros we'd be set.

Working on this:

It's a port of metalua (, a macro + syntax extension system for Lua. Given that CS's grammar is more exuberant than Lua's, the parser combinator library that supports runtime syntax extension requires much more work.

IIRC it's rather "obviously no faults" vs. "no obvious faults".

It's conceptually ugly, but that's what makes non-hygienic macros usable.

A macro which uses a global variable is broken when used in a context which shadows this variable; if functions are not "normal" globals, there is much less chances that you'll shadow them accidentally.

Depends on whether you allow unicode in symbols
