    It's easily done in C++ with boost::regex_replace

    It's also rather easily done in either language using a state machine. Just loop the characters and start counting at each left paren. When the next comma comes up (or the count gets too high) replace if the count indicates the pattern has been matched, otherwise reset and carry on looking for the next paren.
