Hmm.. In C you _can_ avoid type-checking, but it's not that hard to make
it reasonably strongly typed: using gcc the magic flags are "-Wall
-Wstrict-prototypes", and some simple rules.

You still get all the implicit integer and FP conversions done, and that
can be occasionally painful, but not doing them is even more painful, so..

I don't think "void *" is a problem. It just should be used with extreme
caution. I think the "enum is a normal integer" thing is a much bigger
issue type-checking-wise.
