Feature Request: No Useless List Unpack-Repack

[Skylion007]

Description

Saw this is in a discussion on RUFF: astral-sh/ruff#7618

Thread just mentions this construct[*x] as opposed to just calling list(x). Not only is the later more readable, I would assume it's more efficient because lack of arg unpack (we should benchmark it though)? You may want to add a rule to flag this weird construct.

Sounds sensible but let’s not assume and do a benchmark first. dicts can also be constructed via unpack so the rule could cover both.
