Sure, although the distance between them is pretty great.  Any theoretical
major version update to Perl 5.x may require this kind of division, but it's
looking pretty unlikely that Perl 5 will have any more major releases.

Now, Perl 6 is such a major change that it will require the type of
separation you suggest -- but likely not in the way you are currently
envisioning, as it is itself radically different from Perl 5.  So doing the
work right now for zero present gain may actually be a gross waste of time.

However, that was not the point of this particular thread.

To restate myself from the other thread:

If there's only one version of perl[5] in pkgsrc, what's the difference?
