Generally, a rule will return a value directly if it only has one
return value, or a structure containing all the return values if
it has more than one. Evidently something about the token1 rule
is making it want to return multiple values; perhaps it's the
context in which it's used in another rule? If you have a look at
the contents of the structure it might give you an additional
hint.
If it does return a *_return structure, then it will have a member
matching the declared value. (ie. token1_return will contain an
ObjectA called "a".)
