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 https://github.com/D-Programming-Language/dmd/pull/2891

Commit pushed to master at https://github.com/D-Programming-Language/dmd https://github.com/D-Programming-Language/dmd/commit/0ccbc134da6c44b3ae922992d911d8a9dfdaa3c3 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. .
