warnings::register and Perl 5.005?

rrwo has asked for the wisdom of the Perl Monks concerning the following question:

So I distribute a module that uses warnings::register and have the possibly mistaken belief that it works with Perl 5.005.

Just got an E-mail from somebody that they get an error:

Can't locate warnings/register.pm in @INC

So is my assumption wrong? Can warnings.pm be updated for older versions of Perl?

The `warnings` framework is new in 5.6.0, so anything that uses it is non-backportable. And there is no way I can possibly think of to make it work for < 5.6. `warnings` (as most pragmas) is an internal framework -- if you look at `warnings.pm` and `warnings/register.pm`, you'll see that all they do is set some bits and variables. `perl` itself has to do the checking of those things. perl binary 5.005 and back don't do that checking. Sorry :-(. Update: Oops. Put a bare < in the second paragraph, which kinda messed up what it was supposed to say. All good now. -dlc	[reply] [d/l] [select]
