Well that assumption could be considered a bit broken. What if I would
move this metadata to 8-15 bits (0-7 would stay kinds of complex types)
of kind__ filed or if I add another filed to _tagILType to store this
metadata - If I understand this metadata storing business correctly I
would only have to modify the macros in include/il_types.h file to make
it work and nothing else?

If you think this would be such a big performance penalty, then I can
make it configurable through configure so people can choose which one
they would like to use...

Comments? Flames? Suggestions? All are welcome...
