Nope; I had hoped it would be that easy, but as you can see from my
snippet of output, I started irb with -f, which bypasses ~/.irbrc.
ENV['LANG'] also prints nl_NL in irb, so that can't be it.

It does seem that way, as Perl also appears to treat them this way.

However, I'm still puzzled why there's a difference between irb and a
stand-alone script.
