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 think vector operations are designed to avoid turning them into loops.
In (2), this would require several calls to sin().
Really? How would you do Y[] = X[] * X[] without a loop?
