Neither return nor raise use indentation, and you don't get much more 
major than those. Nor do list comps or generator expressions.
Indentation is not appropriate here because it doesn't involve a block of 
code. The whole point is that it just involves a single expression.
But in any case, I'm -1 on any syntax involving ? in Python, and +0 on 
the concept on a conditional return. I suspect it's too specialised to be 
worth special syntax or a keyword, but I can definitely see some uses for 
it.
