Detailed Description
Perl releases will be now every year and updates during year will be containing mainly bug fixes. The release 5.14.0 should be stable release, but 5.14.1 should contain bugfixes for issues introduced in 5.14.0.

Benefit to Fedora
Fedora as bleeding edge distribution should be shipping new release of perl as one of the first distributions.

Scope
Everything will be rebuilt in testing buildroot dist-f16-perltest. 'fedpkg build --target dist-f16-perltest'
 * update perl to 5.14.1
 * update/fix/rebuild all perl modules
 * rebuild all other dependent packages -> file bugs to maintainers
 * in case no basic component is broken, then the packages could be tagged into dist-f16 buildroot

How To Test
Download packages from koji's buildroot dist-f16-perltest or try your packages with rebuild build requirements related to perl.

User Experience
Users could creatively use syntax: 'given' or smart matching ''.

Dependencies
repoquery --whatrequires --alldeps 'perl(:MODULE_COMPAT_5.1?.?)' | sort -u

Contingency Plan
In case some essential packages couldn't be fixed, then would be used perl-5.12.3.

Some packages seem to be unfixable, therefore they should be removed if they don't have any other dependencies.
