Independent of the readability issues associated with any proposal to
expand lambdas out to full function definitions, Guido has mandated
that it shall be possible to parse Python's grammer with an LL(1)
parser. There's no way such a parser can look ahead far enough to see
the double semi-colon to change how earlier semi-colons are parsed.

PEPs 403 and 3150 are still the current "state of the art" for
proposals to add the equivalent of multi-line lambda capabilities to
Python, and both still have fairly major flaws (which is why they're
Deferred rather than under active development).

Cheers,
Nick.
