I'm sure Erlang has fascilities for doing what you're doing without
faking Ruby. What's the value in using a crippled library nicked from
another language? Perhaps the users of the erlang mailing list simply
didn't understand. I don't think I understand either. What do you hope
to achieve by embedding Ruby standard classes in Erlang?

If you're trying to implement Ruby on the Erlang platform, I bet a lot
of people would be interested, but simply being able to fake Array,
String, Range etc. just isn't very interesting IMHO.
