@LeonidShifrin Or you could define General::interr and call Message[ff::interr, args].

comment Error checking and trapping techniques with Throw and Catch
@Rolf Because then when you decide that you need to support alternative languages you're digging through the code. Plus, I'm not sure how this would interact with Off or attempts to find out information about messages.
