I think the misunderstanding is:
$! is not a general purpose error message, it is a magical wrapper
around errno() (read the section in perlvar)
You *COULD* set $! to some numeric value selected from errno.h if
there was one close enough to your message. But a user of your
library getting "Divide by zero error" because that was the closest
thing you could find for "Didn't give me the wumble structure I
wanted" is going to be sorely confused.
Maybe you should be looking at croak and friends, or even taking the
bigger step and start throwing exceptions.

Computer software consists of only two components: ones and
zeros, in roughly equal proportions. All that is required is to
sort them into the correct order.
