Er, am I missing something? How about this?

import sys
pr = sys.stdout.write

pr('Is this less cumbersome enough for you?')

But of course, that doesn't really help you avoid multi-expression 
lambdas, unless you want to write obfuscated code:

def foo(x):
    y = x+1
    print y
    return y

is roughly, but inefficiently, equivalent to:

lambda x: sys.stdout.write(x+1) or x+1

But that's cumbersome and obfuscated, and not scalable at all.
