Hmm, can't think of a way to get rid of the colon without it looking like a 
generator, but perhaps we could tackle the other issues by letting "def" stand 
in for "lambda":

	lambda x: x.y

	def x: x.y

It's shorter, not an esoteric word, and is analogous to a named function 
definition, reminiscent of javascript.  The lack of name/parens separates it 
from the standard form.  Doable, but of course its pretty late in the game to be 
changing lambda, perhaps in Python 4?
