[antlr-interest] DFA's encoded directly in java bytecodes

[Martin Probst]

Hi Terence,

yes, ragnaroek is something like doom. I just used the term because I've
tended to use this construction (break to label) as a faster alternative
to throwing an exception in case something goes wrong within a nested loop
;-)

Indeed breaks can only jump backwards in code, though they are not bound
to loops. If your tool fits ANTLRs needs everything's fine and I'm looking
forward to ANTLR 3!
