Ok, you're obviously right. But $0{'$foobar'} still hurts my eyes,
not to mention how mysterious it may look to newbies trying to
cope with $h{$foo} and $h{foo} as well - unless we are really good
at educating them (but we will be!).

Coming to think of it, why have a named variable at all? If the
match object gets returned anyhow there is no need for a cleverly
named magical variable ($0, $MATCH, ...).
