luaSub is yet another alternative for marrying Lua and macros / token
filters / syntax modifiers. It used to be called luaSuper, and
started its life as ftools/fsyntax scripts.
This pre-release is code complete, but still contains some irritating
bugs. I would be more than happy for any findings and corrected code
snippets. :)
Also, feedback on the comparison section concerning other
alternatives (LuaMacro, MetaLua) is valued.
