This sounds nice, but I can't help but wonder if we can't do one up, and
provide our users with a handy interface that doesn't allow them to run
into run-time parse errors. Something like
(m 'q', action0)
(m $ s $ c f12, action1)
(m $ s $ c 'x', action2)
should be trivial to implement (albeit eating up the namespace rather
ferociously), and would give a bit more safety with only a
slightly-less-pretty syntax. Submaps would require a bit more syntax, but
(m x &&& 'q')
should be implementable. I'm not sure if this would be deemed worthwhile,
but it seems to me a bit more elegant than parsing strings into key
