And never the twain shall meet? So it's long live
HashWithIndifferentAccess ?

A while back I offered the idea of being able to define a key coerce
proc, eg.

  h = Hash.new.key!{ |k| k.to_s }

Such that keys would always be strings. Might someting like that be a
viable solution?

In anycase, I still offer up #rekey.
