Returns the reference type or class if EXPR is a reference, the empty
string otherwise.
I also reindented. I don't think its necessary to go into a discussion
of edge cases nor to rework the example to say "if(ref($r) eq '')" instead
of "unless(ref($r))" because honestly I don't think anyone is going to
go around and change all their code in case some joker sets their classname
to 0.
