Summary
In this episode, Jason explores the challenges of obtaining and passing pointers to overloaded functions in C++. He demonstrates that when working with function overloads, the compiler cannot determine which specific function to select without explicit disambiguation. The episode covers three main techniques for handling this situation: using static_cast to explicitly convert to the desired function pointer type, wrapping the function call in a lambda, and creating forwarding wrapper functions or macros that maintain correct return type deduction.
