I don't have much of an opinion on the subject in question, but I
absolutely disagree with this position as policy.

Releasing a new perl that breaks some form of backwards compatibility
is not "changing running programs out from under them". The user has
to upgrade, a conscious act, and they should look at the change log
and consider the implications and act accordingly.

We are absolutely NOT chained to support everything we supported in
the past. We tend to do so, and certainly much prefer to do so, but we
are not obliged to do so. If breaking backwards compatibility is in
the best interest of Perl then that is what we will do.
