do CPAN authors know the minimum perl required for their modules?
I would hope so.

Really? It seems like kind of a lot to ask every CPAN author. Maybe I'm missing something, but I can think of two ways one would know the minimum version of perl required for their module:

  1. Know the details of each perl version well enough to predict what features their code uses will break and when those features appeared
  2. Try their module out on each successive old version until they reach one that breaks

Neither of which seem like viable options for the majority of CPAN contributors. Now, I would hope most authors know at least one version that their module works on -- that is, the version it was developed against. But that is not the minimum version.
