I think that there are some questions that would need to be answered. For instance, given some composition:

f = math.sin @ (lambda x: x**2)

what would f.__name__ return? What about str(f)?

Lambdas return '<lambda>' so maybe something like '<composed>'? Then str(f) would be ''.

Would be nice to use "", incorporating both names, but that could get unwieldy once you compose a bunch of functions.

Maybe it would be better to have '' for str(f) but 'sin @ <lambda>' for repr (f). So that one can have more info and it would be closer to idealistic obj == eval (repr (obj)).
