I'm not arguing against Ruby.  As I said, it's a nice language.  I'm
just saying that Ruby is not as common as Perl and Python.  For example,
in Debian, Perl is Essential (cannot be removed), Python is priority
standard, and Ruby is priority optional.

I think it's a bad idea to introduce an entirely new runtime, especially
one known to occasionally blow up on less-common architectures, without
some advance notice.  For example, at work I would not be able to deploy
a git using Ruby immediately because Git is an RPM and Ruby is compiled
from source, if it is even present at all.

Also, the only Python script that is shipped with Git is git-p4, which
is essentially optional, since most git users probably do not use
Perforce.  Otherwise, all the scripts in git are shell or Perl.  So this
would be adding a significant additional dependency to core git, one
which is likely not installed on many systems.  Of the systems in the
Debian popularity contest, 41% have git installed and 23% have ruby1.8
installed, with only 16% having the default ruby installed.

My concern is that the Ruby code will end up not being idiomatic, and
people will view it as bizarre and unmaintainable.

for_each_ref could end up being something like REPOSITORY.refs.each,
which would be more idiomatic.  repository.refs would probably be an
Enumerator in that case.  If the decision is made to incorporate Ruby
code, I'm happy to submit some patches to help provide a sane interface,
even though I'm not that familiar with Ruby.
