No need to make any excuses for me. I misremembered, and tye caught it. I hopefully will learn from this and not misremember again.

I regard the POSIX version of exit() to have little to nothing to do with Perl, using it is like using Inline::C and then calling exit() within that.

About automatic destructors, that is a difference of perspective. But any package that wishes has the option of defining an unimport method, which allows the user to notify the package that it is no longer used through calling no. (Admittedly, very few modules implement this.)
