[kelbt-users] [feature proposal] autocommit mode

[Adrian Thurston]

So let me see if I understand ... autocommit would cause all alternative 
parses to be discarded on every reduction, with the option to disable it 
on specific reductions? This would make Kelbt behave like standard Yacc 
by default, with the kelbt behaviour turned on only where needed?
