Could it cap the maximum number of generator calls though? Rejection sampling is technically O(infinity) because you could reject an unbounded number of times. This isn't a problem in practice but it sure is theoretically annoying. With a cap on the maximum number of calls, it would be O(1). |

If you want a number in 1..3, and the generator provides numbers from 1..4, and you want a cap n, then you could model it as a generator that provides numbers in 1..4^n. There's never a way to split that space into three equal parts.
You always end up with unwanted extra possibilities that you still need to handle somehow.
