Bug#457532: ITP: libtask-weaken-perl -- Ensure that a platform has weaken support

[Christian Sánchez <csanchez@unplug.org.ve>]

Package: wnpp
Severity: wishlist

* Package name: libtask-weaken-perl
* Version: 1.02
* Upstream author: Adam Kennedy <cpan@ali.as>

* Description: (follows)
One recurring problem in modules that use Scalar::Util's weaken function 
is that it is not present in the pure-perl variant.
.
While this isn't necesarily always a problem in a straight CPAN-based 
Perl environment, some operating system distributions only include the 
pure-Perl versions, don't include the XS version, and so weaken is then 
"missing" from the platform, despite passing a dependency on 
Scalar::Util successfully.
.
This restores the functionality testing to a dependency you do once in 
your Makefile.PL, rather than something you have to write extra tests 
for each time you write a module.
.
It should also help make the package auto-generators for the various 
operating systems play more nicely, because it introduces a dependency 
that they have to have a proper weaken in order to work.


Thanks.
