If we had followed the math precedent, instead of , we would have set builders, list builders, dict builders, and generator builders.

I was intending to suggest something like that back when comprehensions were first being discussed, but people raced ahead and adopted the term "comprehension" before I got the chance.

"List builder" and "dict builder" make a lot of sense, but "generator builder" not so much -- it is a generator, not something that builds a generator. In fact it doesn't build anything in the sense that the others do. So maybe "generator expression" is the best we could have done.
