PHPStorm 4.0.1 Bug: Color syntax does not work for the array assignment operator

Friendly bug report for PHPStorm 4.0.1. See attached screen shot.

There's no way to color the array assignment operator. It always remains white.

According to the PHP manual, this should be considered an operator:
"For arrays, assigning a value to a named key is performed using the '=>' operator."

Thanks again!
