Step 1 would be to require parentheses around the whole thing (ala 
generator expressions) to make it easier to see where the deferred 
expression ends.

But all my use cases that I can think off the top of my head involve 
'sorted', where it wouldn't help at all because of the need for an 
argument.

So I'd rather see a serious discussion regarding giving lambdas a more 
Pythonic syntax in general, rather than one that only applied to the 
'no-argument' case [1]

Cheers,
Nick.

The 'expression-before-args' version using just the 'from' keyword is 
still my favourite.
