What happens:

My mental model is that "item" in "list" while the way the documentation reads, it is used with "list" in "item" which is just backwards.

What you expected to happen:

if "item" in [list] then do_something.
Deprecate "in" and replace it with the the keyword "has"
I expect [list] has "item" or [BigList] has [AllTheseItems] to be logical. The "in" operator prompts me to get it wrong.
