This thread is a few months old now, but it looks like people were
generally in favor of adding (gcast Refl) to Data.Typeable. I've used
it in real code in at least one place since then (where I just defined
it locally). It doesn't look like it's actually been added, though --
is it planned to go into HEAD eventually?
