I'm curious what everyone thinks about this idea to solve the CPAN
backcompat issue.
Perhaps at module install time, the installer attempts to run the tests for
the module being installed under the assumption that the module is perl7.
If that fails, then on the system mark that the module is perl5, and store
some metadata (somewhere) that the module must be in p5 compatibility mode.

Of course, this would require changing the installers (which probably need
updating anyways) and the addition of some metadata store (unless there is
one already).
