Parameterless extension method without parentheses is not called unless explicitly qualified by this about scala3 HOT 3 CLOSED

Yes, that's as specced. Extension methods require an explicit receiver.

from scala3.

Thanks,
I wasn't decided between using empty parentheses (which is unnecessary) or qualifying with this (which is ugly).

There was an old scala 2 ticket for the same intuition for implicits (by paulp).

I agree that it's too bad there is no warning about the mistake. The error in "statement position" is very helpful.

I had to remind myself why -Wnonunit-statement is also unhelpful. (The warning is ignored by IterableOnce et al.) As a mere lint, it could special-case foreach.
