[Python-ideas] Re: Adding a "once" function to functools

The connection is very obvious after you know about it. And probably you can guess the meaning if you see an @once decorator in someone's code. But it's less clear that a person who hasn't seen the word "once" used this way will think of searching for it when they want a way to cache the return value of a function. https://docs.python.org/3/library/functools.html#functools.lru_cache
