So how do things work at the global scope?  Unless there is some good reason
to make the global keyword required there, it would be nice not to.  Then
"normal" global function and data definitions will not be affected.

It seems that this globals issue is tied with whatever the module system
becomes.  It's hard to decide about one without the other.
