[Catalyst] Patch: display plugin versions

[Ovid]

Hi all,

I wasn't sure what format patches should be submitted in so I'm doing
this both inline and as an attachment.

The following patch displays version numbers, if found, for loaded
plugins when Catalyst::setup is called.

--- lib/Catalyst.pm.orig        Tue Dec 13 12:30:26 2005

         {
             no strict 'refs';
-            @plugins = grep { /^Catalyst::Plugin/ } @{"$class\::ISA"};
+            @plugins = 
+              map  { $_ . ' ' . ($_->VERSION || '') }
+              grep { /^Catalyst::Plugin/ } @{"$class\::ISA"};
         }
 
         if (@plugins) {

I've found this useful when trying to debug a Catalyst app one someone
else's machine and I'm trying to figure out if he has different plugin
versions.

Cheers,
Ovid
