Problem statement
Ensuring that callback functions are type-safe and compatible with a given context is crucial in modern programming. You are tasked to create a utility named CallbackValidator that allows users to check whether a given callable object (such as a function or lambda) is compatible with a set of argument types and a return type. The CallbackValidator should provide a ...
