How many beginners know they want to call a function only once?
More than the number who know about LRU caches.
Ethan, are you objecting to a self-descriptive name because it is too
confusing for beginners and lru_cache isn't? Because that's the argument
you seem to be defending.
I'm objecting to using "beginners" as the basis for name choices for advanced
topics.
Aside from that, `once` is a fine name. I'm sure it means that a function can
only be defined once, and subsequent definitions will either be ignored or
raise, right?
>>> @once
... def my_unique_function(...):
... do_something_cool()
...
>>> def something_else():
... pass
...
>>> def my_unique_function(...):
... # uh oh, duplicate!
...
RuntimeError - duplicate function name detected
