Agreed.

FWIW my current solution is: `mv ~/perl5 ~/perl5-5.40; cpanm --installdeps 
<whereever I needed deps for>` (repeat for every carton local/ as well)

It would be great if cpan-like tools installed all modules in a 5.40/ 
directory under ~/perl5 (or similar), and perl itself came up with 
something like "This is perl 5.42, you only have Object::Pad installed for 
5.40, fix using this command: cpan XXX"
