using the merge keyword

[Adam Smalin]

I have two possible outcome. If it A works i rather then A then B however i
notice merge and try it out.
It looks like it doesnt get rid of my conflicts. I though the point was it
would run that code when an conflict occurs. Then i looked at the manual and
it looks like it just 'prints' them?? (sounds nearly useless)

Am i using merge wrong or am i missing something?

    | '{' A '}' %merge <AB> {$$ = A(1, $1); }
    | B       %merge <AB> {$$ = B(0, $1); }
