No, it is not ok to get success from 'use foo v1.2.10' when foo's
$VERSION is v1.2.3_1 -- especially when a version.pm comparison would
tell you that v1.2.10 > v1.2.3_1.
If version.pm gives a different result than use(), version.pm is wrong.
IMO, it's not even worth trying to sort through the scenarios where
using two different comparison mechanisms is going to cause failure.
I'll guess that the only reason this isn't already a complete mess is
that no distro besides SVK has used _ in extended versions.
Can anyone give a reason for use() to treat version.pm objects and
v-strings differently?
