function isunhookable(closure: (...any) -> (...any)): boolean

High-Level Overview

isunhookable returns true for every function that is considered unhookable; this means you cannot call hookfunction with it being hookWhat⁣; this does not limit you to calling hookfunction with it as hookWith. You can make functions unhookable by utilising makeunhookable.

Low-Level Overview

Internally, an std::vectorof all the unhookable functions of the session are kept. When a new one is made unhookable, it is added to the vector.

When validating if it is hooked, we check our list and validate the c.ffor C closures and l.pfor Luau closures; if any of them match, the function is considered unhookable, the result of it being pushed onto the Luau stack.
