Re: checking arbitrary bounds

Surely someone must've run into this before. I want to write a
function that combines the functionality of Low() and High().

The difficulty will be that Low and High are compiler-magic functions. Their implementations are built in to the compiler, so you can't duplicate them in normal code.

I usually just let the compiler insert my bound-checking code for me by enabling the range-checking compiler option. And any explicit bound-checking occurs within Assert statements.
