Function definitions and stuff like that I agree you probably aren't going to get much from it but memorizing large parts of the standard library is somewhere you could since in a lot of cases you aren't going to be using a lot of parts regularly but when you need them you'll save a lot of time if you have them in your memory vs having to google/check docs.
