Avoiding boilerplate by using immutable default arguments (vulwsztyn.codeberg.page)

Hi, I recently realised one can use immutable default arguments to avoid a chain of:

def append_to(element, to=None):
    if to is None:
        to = []

at the beginning of each function with default argument for set, list, or dict.

Upvote for the sanity check.

As the OP mentioned, this is a proposed/draft feature that may or may not ever happen.

With these kinda posts, should start a betting pool. To put money down on whether this feature sees the light of day within an agreed upon fixed time frame.
