Exporter change in bleadperl breaks an Exporter test in the previous Exporter pkg on CPAN

[andk]

Module: Exporter

Description

Bleadperl has Exporter 5.79 since commit v5.41.8-94-g92096305f2

CPAN still has Exporter 5.78 as the current one

If one runs the 'make test' for the TODDR/Exporter-5.78.tar.gz distro, one gets a fail like illustrated in http://www.cpantesters.org/cpan/report/1ea91aba-1b88-11f0-bebf-970cda0fe8b3 ; the question is: is this intentional or is it a regression?

Steps to Reproduce

(enter the cpan shell with e.g. PATH-TO-YOUR-5.41.10/bin/cpan, then within the shell enter)
test TODDR/Exporter-5.78.tar.gz

The above fails the test like in the link above, i.e. the output contains:

 "quux" is not defined in %Foo::EXPORT_TAGS at t/warn.t line 37.
	eval {...} called at t/warn.t line 37
t/warn.t ...... 
Failed 1/2 subtests 

Expected behavior

The test should probably produce a PASS like it did with 5.41.8. Or, if it is intentional, this should probably made clear by providing a 5.79 on CPAN with a passing test.

[haarg]

Downgrading to a module version from before the perl release won't always work. A change was made in core which required an update to Exporter. This is the expected process, so there isn't really anything wrong here.

There are a number of blead-first dists that should be released to CPAN, but that is meant for the benefit of older perl releases, not for the latest release.
