I guess I am confused. How do we know this? How can we be
certain that there shall not be any further binary incompatibilities
introduced in Perl? The fact that the upstream releases are
maintianing the versioned component seems to imply that no such
(implied) promise has been made by the perl 5 porters group.

Hmm. The statement is indeed true, I just seem to be too dense
to see how it applies. Say the new Perl (released in jan 1999, say)
is binary incompatible to 5.005. I have a module, foo. How does this
scheme prevent a recompilation then?
Are we just putting all our eggs in the basket that despite
the record, there shall never be any incompatible perl releases?

This, I agree with. The solution proposed either is a kludge,
or I am missing the point.
Me, I would create the current and all future versions of Perl
which are binary compatible to have the link:
/usr/lib/perl5/$arch/$version --> /usr/lib/perl5/$arch/<code name>
No modules need be recompiled when the new perl comes out,
since all of them really reside in <code name> dir.
When a new incompatible Perl comes out, we change the <code
name>, and recompile.
What am I missing?
