* A function is an implicit binary operator between two "noun"
* tokens—typically between a variable on the left and a group on the
* right, in which case the function's precedence is inferred from the group.
*
* Examples:
*
*
* - {@code f()} → {@code f (0)
}
* - {@code f(a)} → {@code f a (1)
}
* - {@code f(a, b)} → {@code f a b (2)
}
* - {@code f(g(a))} → {@code f g a (1)
(1) }
