in reply to Why does Perl have typeglobs?

A long time ago, it was a way to carry around filehandles. Perl 5.8 (I think) allowed lexicals to hold filehandles, so this use died out.

Most useful thing I've found is to make a list of simple accessors in a class:

{ my @ACCESSORS = qw{ foo bar baz }; for my $slot (@ACCESSORS) { no strict 'refs'; *$slot = sub { my ($self) = @_; $self->{$slot}; }; } }

But even this has tended to go away with meta-object systems like Moose (which do similar things under the hood).
