I think it's rather elegant in its own way. There's
something exactly analogous in Scheme, where you can
(define (f (g x))
and it gets macro-expanded into the corresponding
nested sequence of lambdas. (The really elegant part
about it in Scheme is that it's not a separate feature --
it just automatically falls out of the way define is
defined in terms of lambda.)

I would implement it by compiling it exactly as
though it were written out as nested defs.
