Hm.  We do late binding of globals.  Why shouldn't we do late binding
of locals?  There are lots of corners or the language where if you
expect something else the actual behavior feels like a bug, until
someone explains it to you.  That's no reason to compromise.  It's an
opportunity for education about scopes!
