Summary
This episode demonstrates how to build a high-performance domain-specific language (DSL) for matching bit patterns in C++. Jason implements a BitPattern class that allows developers to express bit matching with a string-based syntax where '1' and '0' represent specific bit values and 'X' represents any bit (don't care). The implementation uses consteval, bitwise operations, and operator overloading to create a zero-overhead abstraction that can be used in both runtime and compile-time contexts.
