(1) Y[] = X[]*X[];

With gdc 4.4.6,
(1) compiles and executes as I expected, whereas
(2) is not allowed (fails at compile time).
Why?

The semantics of (2) is unambiguous,
and it works perfectly well in Fortran90.
Allowing (2) would make D really attractive
for formula-heavy mathematical work.

I like it, but there is a problem:

(2) is already valid code if you have these two overloads:

float sin(float x);
float[] sin(float[] x);

So with your rule it would be ambiguous.
