It’s actually more like ‘cpan -i ANDK/CPAN-1.94_56.tar.gz’.

I do. I’ll try to prepare a few, if I have time.

I was actually thinking of using B::Hooks::OP::Check for Classic::Perl, but I decided against it, as I want it to be easy for people to put ‘use Classic::Perl;’ at the top of their scripts *before* upgrading perl, to make the transition easier (Classic::Perl’s raison d’être).

No. That’s a hard one to solve. In cases like that, I simply bundle up the dependencies.

I should have noticed this sooner before the trend started. :-( I was hoping eventually to get all these modules switched over.
