Don't use the constant pragma. It will 'constant'ly trip you up with problems like this. Use ordinary variables in all caps instead.

The reason your code is breaking is that '=>' stringifies the left argument. The constants are actually implemented as subroutines, and they are not being called. You can fix this by saying "ROTATE() =>" instead of "ROTATE =>", but why bother? Just use variables.
