What about Erlang..  Errrrrr
But I have not so much interest in dynamic typed languages so have done
little research on it.
Been meaning to experiment with APL or learn more about it too.

Those languages that have special symbols or require a special keyboard I
am sure turn lots of people off.

This email could go into fpc other i suppose
