Summary
This episode explores how mutable lambdas with captures can function as self-contained state machines. Jason demonstrates this concept first with a simple Fibonacci sequence generator that produces successive values with each call. He then expands the idea by implementing a more complex integer parser state machine that handles input validation, negative numbers, and maintains state across multiple calls, leveraging lambdas' ability to maintain internal state between invocations.
