Actually, *foo{IO} only contains filehandle foo, dirhandle foo, and socket foo. There dosen't seem to be a way to get a reference to a format, the best you can get is an entire glob: *foo
Thanks, that goes in the bucket of odd facts I might need
some day.
However I would also suspect that this area of Perl has
not been extensively tested. I would not be suprised if
the intrepid explorer encountered a few interesting
features...
