 * either takes a function as an argument or (may) returns a function.
 * If the return is an identity, e.g., `function(x) x`, this is not considered higher-order,
 * if no function is passed as an argument.
 * Please note that inspecting higher order functions can be sped up (if queries multiple times) by providing an inverted graph as well!
