[Haskell-cafe] Mo' comprehensions

[Diego Navarro]

I was solving some programming puzzles today[1], and found myself
pining for Map comprehensions.

Maybe there should be a Comprehensible class that's automatically
mapped to comprehension syntax. It's rather odd to have them only for
lists. That would be both more general and more elegant than just
bringing back monad comprehensions.

Is there any obvious reason why this wouldn't work?
