## About me * Canadian * Licensed professional engineer * I like twisty puzzles  <!-- .element style="position:absolute; height:75%; right:0; top:12%;"--> * Working in C++ for 4 years * On WG21 since 2023 * Run Winnipeg C++ Developers

Function overload resolution

Template specializations

Template argument deduction

Class template argument deduction

Conclusion

## C++ has pattern matching! * Function overload resolution * Template specializations * Template argument deduction * Class template argument deduction

## I read the standard so you don't have to * [over.match] * [temp.names], [temp.spec.partial], [temp.spec] * [temp.deduct] * [over.match.class.deduct], [dcl.type.class.deduct], [temp.deduct.guide] * Cppreference is also an amazing resource

## Takeaways * We already have pattern matching! * The general rules can be quite elegant * ...but the edge cases can get gnarly * Analogue reasoning about your code is a muscle * Get curious, exercise that muscle * Appreciate how far C++ has come

Thank you!
