If I need numbers It's doesn't mean that user will see
them. I'm just going to put unique number to each tree
shape. And use with maximum value to remove
disambiguos situations.

I don't know. Do you know any languages where n-arity
operators are built-in?

Actually C++ was going to have them, but it wasn't accepted.
Gotta look at that paper.

    Bad English. Please try again with simplier words :)

I'm already using this. But aforementioned examples were
exclusions where that rule doesn't work.
