Description: Since it seems there is not going to be a quick solution to the problem of modules running under perl < 5.6 with "use warnings" (see 278753), I thought I'd add this piece of code to the snippets. Courtesy of Podmaster. Documentation added for those monks not really familliar with BEGIN, GLOBs and %INC.


# Do this at compile time


#  Check if there is a warnings module available

    eval {
        require warnings;

#  If not, create dummy "import" and "unimport" subroutines

    } or do {
        no strict 'refs';
        *warnings::import = *warnings::unimport = sub{};

#  Make sure no attempt will be made to load the "" file ev
+er again

        $INC{''} = '';

    The fake import() and unimport() is not necessary actually.

    Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.
