It's in my queue of projects, right after a robust M::B in 5.10.1 and
CPAN Testers 2.0 and arbitrary automated CPAN regression testing for
any distribution.  I wrote CPAN::Reporter::Smoker for "turnkey" CPAN
testing. I would love to see the same thing for regression testing and
then perl testing.

But I don't think automated smoking of a configurable subset is
entirely necessary.  It helps, yes, but I think a cultural shift needs
to happen first.

But is it really any worse than today in terms of the end result?
Today everything gets merged willy-nilly and no one knows if things
are really stable or not.  There's no responsibility for stability --
it's commit and pray and then the pumpking pays for it.

If a merge proves bad, rip it right back out, chastise the author and
make them provide more evidence of stability in the future before
accepting their merges.

Let's make stability the norm and instability the exception, not the
other way around.
