In order to solve your second problem, what you probably need is an
ambiguous grammar.

    VERB: polish_give OBJI_ACCUSATIVE LIV_DATIVE
    VERB: polish_give OBJI_ACCUSATIVE SOMETHING
    VERB: polish_give SOMETHING LIV_DATIVE

In order for the second and third option to be considered, parse trees
for earlier ones must be taken out of the game by letting functions
return nil.
