Summary
This episode explores advanced techniques for creating interactive stateful lambdas in C++. Building on a previous episode about basic stateful lambdas, Jason demonstrates how to enhance lambda functions to not only maintain state between calls but also expose that state for external interaction. Using a Fibonacci sequence generator as an example, he implements a lambda that returns a custom struct containing references to the lambda's internal state, allowing callers to both access and modify the sequence generation. The technique is further refined with operator overloading and additional convenience methods to provide a more natural interface for navigating through the sequence.
