If we were talking about code that was going to end up in the PG
distribution, I'd kind of want it to be in C or Perl, just to keep down
the number of languages we're depending on. However, it's not obvious
that a tool like this would ever go into our distribution. I'd suggest
working with what you're comfortable with, and we can worry about
translation when and if there's a reason to.
