At what point should I consider changing from a StringSwitch construct to something more efficient? TableGen has a few of them. In particular, the switch for looking up a bang operator has about 40 cases, all short strings.

One trivial improvement would be to split it into two StringSwitch's based on the first letter of the operator name.
