( #3333=superdoc: print w/ replies, xml ) Need Help??

Cool.

I had previously convinced myself that because BEGIN requires a block, I couldn't fake out 'use warnings' for people who don't have it but then I realized this works fine:

BEGIN { if( eval { require warnings } ) { warnings->import(); } else { $^W= 1; } }
because the pragmas already expect to be inside of a (invisible) block and so apply themselves to one block further out.

I like this method because it allows the user to install a back-ported warnings.pm or bytes.pm or whatever and use it if they want to and I don't have to trust my knowledge of when the module was added. (:

Anyway, it is another way to do it.
