works in 2.064.2, fails in 2.065
import std.complex;
void main(){
  auto a=[Complex!double.init];
  a[]*=a[];
}

I'm not sure this is supposed to work... Structs with overloaded operators
generally don't work with array operations.

I don't see why it shouldn't be allowed (besides the fact that it did work up
till now). Without this complex numbers are very much 2nd class citizens for
example.

Yes, but unless the 2.064 behavior was intentional, this is an enhancement and
not a regression.  I remember this being discussed before but I don't know
where.

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.
