I should have said the perl 5.0 family. Including 5.004 which is still
being maintained by the Perl maintainers. Perl 5.005-04 just came out
in 2004 by the way. perl 5.6.2 came out in Nov 2003.

There were major structural changes in perl 5.0 and 5.6 The changes
going from 5.6 to 5.8 and 5.9 are much less.
You can take it as a given that anything that runs on perl 5.005-04
will run on all perl 5.0 versions, anything that runs on perl 5.6.2
will run on all 5.6 versions, etc.
The whole reason that the perl project maintains 5.0, 5.6, 5.8 and
so on is that they know that there's systems that have lots of tested
programs that have been tested under 5.0 and the system maintainers
have not yet gone through the process of testing all that software
on newer perl versions. Despite what you probably believe, when
an organization has a server that is running fine, they are not
frothing at the mouth to upgrade it to the latest version.
This is why IMHO that perl is not a good choice to use for building
large systems, not because the perl maintainers don't understand
the importance of backwards compatability, but because too many
programmers like yourself simply don't.
If I was building a system that was ONLY going to use perl and
the modules supplied with it, and NOT use any other 3rd party
modules, then I would consider using perl, there wouldn't be
anything wrong with it.
But most of the perl scripts out there use many 3rd party modules
(and I understand why, it saves them time) and that is where you have
the problem, is with those.

I wasn't talking about 1999 software I was talking about 2004
