Sorry to intrude, but, would it be possible for you to:
 - explain a bit algorithm on which your typeof works since the implementation 
is too messy to basics be stripped out
 - explain why is your algorithm so slow - on my Athlon 2200 and VS7.1, it 
takes about a second per typeof too be processed, which is, in my opinion, 
quite unacceptable. What is the speed bottleneck and is there a way to strip 
some features (function pointers, for example) to fasten compilation?

Thanks.
