[issue36772] Let lru_cache be used as a decorator with no arguments

[Stefan Behnel]

Stefan Behnel <stefan_ml at behnel.de> added the comment:

I'm generally ok with such APIs. It seems needless to require

  @lru_cache()
  def f(): ...

when a simple decorator would suffice. I think I might decide otherwise in cases where almost all usages require arguments, but if the no-arguments case is common (and there is no ambiguity in the arguments), then I prefer not requiring parentheses.
