void foo(T)(T[1] b) {
    b[] = b[] ^^ 2;
}
void main() {
    import std.stdio;
    foo([10]);
}


DMD 2.065rc1 gives:

test.d(2,9): Error: invalid array operation 'b[] = b[] ^^ 2' for element type
int
test.d(6,8): Error: template instance test.foo!int error instantiating


Expected error message:

test.d(2,11): Error: must import std.math to use ^^ operator

I'm guessing this was caused by

fix Issue 12197 - 'invalid array operation' errror message with valid array
operation

Make explicit importing std.math unnecessary for pow expressions.

Currently front-end does not enforce std.math module existence. Therefore,
there's not also necessity to explicitly import std.math in user code.
