I did not (for reasons mentioned below), but I will. As I said, this
is a lazy question :-)

But projects which were not updates since luaforge demise make me
worry. Also, this project depends on LPeg and was not updated after
LPeg was rewritten by Roberto — which is a bad sign too.

...Well I'm looking at the Leg docs now, but I do not see AST-related
stuff. Looks like I'd have to build it myself if I will go with Leg.
Is there anything higher-level out there?
