Lightning Talk: Spanny: Abusing C++ mdspan Is Within Arm’s Reach

by Griswald Brooks

Summary of the talk:

While the canonical use case is to refer to a stack or heap allocated data, the accessor policy allows you to inject any side effect allowing the data to come from anywhere... like a robot arm inspecting bins.
