That will have a performance hit unless it's genuinely an exceptional
case. (Well, it'll have a hit then anyway, but that's not the point.)

Anyone implementing this should look into labelled breaks, which
can be used more safely than goto in many of the same situations. Not
having looked at the Snowball code generator, I can't be certain this
will solve all uses of goto, but unless Snowball is outputting really
hideous code it should do :-)
