It's not clear to me why people prefer an extra function which would be

to do it.
Indeed, and if you want to guarantee that a function is executed exactly
*once*, then a decorator called *once* is that Obvious Way.
How many beginners do you know who even know what a LRU cache is?
How many beginners know they want to call a function only once?
