Re: symbol for lookup

Whatever happened to the proposal of using . as prefix?

I guess, the same that happened with the proposals to use "+" as a prefix, or proposals to change sides and use "->" (https://mail.python.org/archives/list/python-dev@python.org/thread/F22RLCDGK...) or ">" to mark variables to be bound.

If memory serves, the main objection was about it being hard to see, but is it really? We use fixed width fonts for a reason, and there are other places a dot is quite critical (has any php programmer ever mistaken a .= for a = ?) without it's size ever causing issues.

I think . is visible enough while being aesthetically inoffensive. Am i missing some problem or important past objection to it?

It's logically rather offensive. Dot is "structural sub-element" operator. Given things like: from .foo import bar a.b = 1 something like: sth = "currently, I'm going to match by this value" match foo: case .sth: print("This looks really weird!") looks really weird. -- Best regards, Paul mailto:pmiscml@gmail.com
