Considering its sanity damaging effects in C++, not a great idea!

You can't do template meta-programming without some form of templates, 
which I doubt we will ever see in C.

Have you ever tried any serous meta-programming in C++?

That will depend on your definition of "serious meta-programming".  Even 
then, I don't see how your opinion on template metaprogramming could vary 
depending on someone else's experience with template metaprogramming.

i suppose he was wondering if you'd dug deeply into TMP if you couldn't see the sanity bending. What was it... concepts they had to drop from the C++ standard because even very smart people were struggling with it.

from wikipedia: "the syntax and idioms of template metaprogramming are esoteric compared to conventional C++ programming, and template metaprograms can be very difficult to understand"

though it goes on to say programs can be shorter and esier to understand by people familiar with TMP
