Indeed. But code-sharing in generics is a separate issue from throwing
away dead code. Are you saying that _everything_ in the generic was used
50+ times? Wouldn't throwing away the dead code at least get rid of
some of the extra stuff?

I wonder if folks out there in net-land could check their favorite compiler
documentation and ascertain the general kinds of global optimizations
done. A general summary of compiler families in this regard would be
helpful to all concerned. I'll take responsibility of summarizing, though
I think your answers would be better posted than e-mailed to me.

Does your system code-share generics?
Does your system throw away dead code?
