Excuse me if I disagree here. If I were to understand this in real-world 
code, I cannot imagine what will happen here.

A "yield" within a comprehension is like a "return" in a comprehension. 
It makes no sense at all.
Also a "yield" and a "return with value" is also rarely seen.

Comprehensions build new objects, they are not for control flow, IMO.

Cheers,
Sven
