This change was introduced by fixing bug 11376.

If an used array-op is not directly implemented in druntime, compiler will
implicitly generate a function to implement the required array-op by using
for-loop. So, if the array-op operand properly supports arithmetic operations
(+, -, *, /, ...), corresponding array-op should also be accepted.

So, this is really a regression IMO.
