Interesting.

However I think it would be better to turn a ruby string into an erlang 
list, rather than an atom, for two reasons:

(1) It more closely matches what happens in Erlang

1> Foo = "abc".
"abc"
2> hd(Foo).
97

(2) I'm not an Erlang expert, but I think I read that Erlang has the 
same atom-exhaustion problem that Ruby has with symbols: namely that 
once an atom has been allocated it cannot be freed. So it is not a good 
idea to keep calling list_to_atom on random strings provided by 
untrusted users.

I'd still expect Ruby symbols to be mapped to atoms, of course.

Regards,

Brian.
