Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
A technical article presenting a compact string formatting library implementation in C++ that uses only 65 lines of code. The library was developed for a video game project and provides basic string formatting functionality with {} placeholders, designed as a minimal foundation that can be extended with additional features.
