We have seen [... where I = 0 then I+1 while I < 100]
proposed, but that's not actually as general as a functional
language should be. What's needed is a general 'unfold'
proposal, and we've had that for a while too.
Semicolons in Erlang always have either the actual or
the metaphorical force of "OR", so they make no sense in
