I think the whole discussion about the concept and meaning of
zero-dimensional arrays is mostly irrelevant to the original
issue. The original issue is a *syntax* question: should
x[()] be written as x?
And from a syntax perspective, it's a bad idea. x is much
more often a typo than an intentional attempt to index a
zero-dimensional array. The compiler should continue to treat
it as a syntax error.
