We had about the same discussions in the programming language domain years
ago. One outcome from this was - at least for me - that

(a) the language semantics should match intuition and the most
common problems. This is where the art of language design
comes in.

(b) there should be an institutionalized way to modify the default
behaviour and coerce it to a specific solution whenever the
language had "loose, don't care" semantics.

That's what pragmas usually do.

PS: (c) There should always be more than one way to do it and it should be fun. :-)
