Well duh, any sub reference in the symbol table is no longer
anonymous and can be used as a method.
Also, every subroutine in Perl is a closure. It's just that some of
them don't close on any variables.
my $foo;
sub bar { # also a closure
$foo;
}
This is a pretty standard way to generate subroutines which are
mundane to write, like, for example, log event handlers, or
convenient methods.
Class::Accessor also does to generate accessors.
