Why would implicit local variables need unique names? This can be
implemented by preventing identifiers named '_' to be inserted into the
symbol table.
Of course, it doesn't HAVE to be that way. I would think it would be
easier to implement. I don't know enough to judge which is easiest, but it
doesn't sound trivial either way.
