Uhm, I don't know.  What if the following was run in parallel:

	{Foo, Bar} = {fun(X) Bar(X) end, fun(X) Foo(X) end}

ok, so its an infinite loop.  But when a fun is compiled, if the fun
could automatically assume that all variables which are going to be
bound as a result of the fun being created are also bound, as if the
had been bound before the expression?

This would make self-recursive funs easier to construct, as you would
no longer need to pass the fun to itself.

It doesn't solve the problem of forward references however.  And I think
we all agree, we'd just want the shorthand notation back, which is the
same syntax we use today.  :)
