This doesn't make sense to me, because those are not variables that
are currently in-scope.  They're only in-scope inside the sub you're
calling.  And in fact if you require the prefixes, you're *continually* going
to be writing code that looks like:

	foo( $name : $name, @addresses : @addresses, $email : $email );

because you're often going to name in-scope variables the same thing as
the parameter names for the sub.

I prefer:

	foo( name : $name, addresses : @addresses, email : $email );

even though I'd rather that:

	foo( name => $name, addresses => \@addresses, email => $email );

"just worked" somehow.  Magical thinking, I know.
