proposed syntax for multiline anony-functions (hopefully?)

Agree.

Lambdas are perfect in Scheme because they are idiomatic in it. They
carry a visual meaning and flow nicely with the parentheses and the
indentation.

Multiline lambdas would look out of place in Python. Also, they don't
buy you anything functionality-wise or expressivity-wise.

Lambdas are visually absolutely horrible in Java (which doesn't need
them) and C++ (which is in dire need of them).

However, it would appear lambdas are all in the rage among programming
languages, and I could think of far worse fads (XML, shudder). So it may
be that Python will eventually have to give in to multiline lambdas
because of the marketing pressure.
