About the Lab  Overview How to description? Greetings fellows monks, Today (as seen from here) I posted a question readline error behavior. Answers same to point me to return undef and set $!. This in turn raises another question. Here it is. Looking at perlvar it appears that $! can be set, so setting the underlying C variable errno. Nevertheless, this only takes into account the numeric side of $!. If one affects to $! a number not defined in errno.h, the stringification of $! gives Unknown error n, where n is the numerical value of $!. Is it possible to modify the stringification of $! (obviously without touching at the perl intrpreter code) to include user-defined messages? Obviouly I'd like to have these custom messages localized accordigly to the locale setted by the user. Am I daydreaming in hoping there is a way to achieve this? Thanks for helping
