The following ought to solve that problem by matching either 0 or 1 occurrences of the double quote after the equals sign:

It doesn't. The string still shows up in $MATCH and $TESTVAR with both quote marks intact. WHY?
The \/ operator has the side-effect of making regular expressions to the LEFT of the \/ match the MINIMUM possible string, and expressions to the RIGHT of the \/ match the MAXIMUM possible string. So any RE on the left that ends with a wildcard will always prefer to treat the wildcard as a non-match UNLESS that would cause the RE on the right to fail.
