  I'm not meaning when the comprehension is invoked, but during each iteration of the loop within the comprehension. When doing something like `map(lambda x: 2+x, range(100))`, there will be 101 frames created: the outer frame, and 100 for each invocation of the lambda. Whereas `[2+x for x in range(100)]` will only create 2: one for the outer frame, and one for the comprehension.
