C++Now 2026 Lightning Talk

Michael Caisse said something to the effect of:
 
At BoostCon, people were presenting the tricks they used to implement their libraries. Not for the tricks in and of themselves, but as a tool to solve a problem. If we just take the trick as a solution, that's not enough. We need to understand the problem.
 
However, this talk is only about a trick.

## This talk is about * Playing around with code - Ben Deane * "Wishful thinking. Think of the API you want to use [and make it]" - Michael Caisse * Let's have fun with a syntactic ambiguity

C++ syntactic ambiguity

A trait to add two numbers

Codegen

## Can you make code that looks like run-time template parameters? * Yes * Should you? * Maybe... * But not in production code, please

## Conclusion * Play around with code! * You may find something useful * ...or you may just enjoy the journey

Thank you!
