And looking at the awkwardness that option-as-meta has provoked with
Aquamacs and layouts where option is used as a dead key, he has a
point--that behaviour really breaks on keyboards where option is needed to
generate a character.

But his code already looks at the currently active layout for keys with the
control modifier; it should be possible to check if option + key is bound in
the OS X keymap when such an event comes in, and to pass the corresponding
character to the event handling code rather than option + key. That seems to
me to be the least surprising behaviour.
