Would be cool, thanks!

I can care for this (with some wise words from #toolchain).
What can be a reasonable approach for providing the "around"?
Using Class::Method::Modifiers and suggest bundling for distributions for
ancient environments?
As far as I see it has only core dependencies...
inc::latest does a great job for bundling. It does exactly what I want to reach
with ExtUtils::BundleMaker.
I tried it in LMU 0.400_010 - this sounds being a reasonable approach for
distributions using ExtUtils::MakeMaker::Extensible.
