Sounds like a job for the token-filter patch ... it seems doable in
LuaJIT, pretty similar code.. Then one can do like C (another fine
language with no constants) and preprocess the problem away. I suspect
that LuaMacro can help to bridge the divide [1]

1. I know, we were all told that the C preprocessor was a bad idea, no
lexical scope, and so forth. But macros are no worse than globals
really, and strong religious feelings should be kept out of
engineering ;)
