And in fact you do that in a number of places. And actually, "=" is not a comparison operator. It's an assignment operator. You most likely need to review your entire filter to make sure you use "eq" for string comparisons and "==" for numeric comparisons, rather than "=".
I've learned to code equality comparisons with the constant value on the left to make it easier to catch an inadvertent use of = where I meant ==. I don't know how effective that is in Perl but it will throw a compile-time error in C/C++ if the left operand is non-modifiable. So "2 == x" instead of "x == 2", for example.
