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.

\rho

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