Yeah, I've done one myself. It sucks. (Not to mention the fact that C and C++ 
will let you define new keywords, which are parsed differently depending on 
their type... eeah. What does '*fnord' mean? It depends on whether 'fnord' is 
a type or a value...)

The two things I worked out are:

(a) only look at the code *after* the preprocessor has had a chance to run, 
and

(b) whenever possible, cheat like mad. You don't need to understand 
everything, just enough to do the job.

Lua's a much simpler language and should be anything like as hard.
