Let's not talk hypotheticals.  git-svn.perl (+ perl/SVN/*.pl) is
absolutely massive.  It's an incredibly useful tool in that it
actually works, and that there is nothing replacing it in the
foreseeable future.  This monster was written almost entirely by one
brilliant person, and nobody is going to rewrite it.  We don't start a
huge discussion about what languages are "approved" before accepting
such a contribution: if the contributor wants to write something in a
dominant language (Perl in this case), and it's going to be useful, we
merge it.  End of story.

All this planning is a colossal waste of time, in my opinion.

Why are we discussing something that is indeterminate?  It is
impossible to foresee the future, but that is no reason to freeze
_present_ development.

Various programming languages have different philosophies, and have
grown in different ways.  What matters is that some of them have a
large number of users, and we're talking about one such example.

This has to be a rhetorical, because I don't imagine you expect anyone
to predict the future.  As Felipe already pointed out Ruby 2.0 is a
good sign.

Nobody claimed that "press coverage" is a good metric.  We can only
talk about facts, and Felipe already showed you a TIOBE index graph.
If you have overwhelming _evidence_ that Ruby is a weak language that
will die soon, share it: otherwise, I see no value in this discussion.
