Natural grammar, OK...

X drove a dagger into his leg.  -- accusative :-)
Y used the kitchen knife as weapon.  -- instrumental

  procedure Pick_for_Attack
    (Self : in out Person; Instrument : Weapon);

  procedure Fight  -- symmetric relation (now)
    (Self : in out Person: Other : in out Person);

There is no end to constructing contexts, very general
ones and very specific ones, and hardly ever complete.
Some will prefer one or the other. Others will present
an example with generality of wording reversed.  That's
not statistical evidence. I'll prefer convincing evidence
when deciding for or against a set of grammar rules.

But accusative and instrumental are good examples.
Consider verbs and adverbs in some programming languages.
