Lisa Lippincott: What is the basic interface?

When we read a function declaration, what expectations do we have of the function? What requirements and limitations do we take for granted? Our unspoken assumptions about function interfaces present an obstacle to precise reasoning about programs.

Here, I will delve into the nitty-gritty procedural logic of function calls in C++, with particular emphasis on the things that often go without saying. I will present some suggestions about how we can make these implicit expectations precise, and how we can express deviation from these expectations in current and future versions of C++.

This presentation will be a companion to my C++Now 2015 session, "How we reason about procedural programs," but no knowledge of that material will be necessary.

Wow! This is a must see for anyone seriously interested in the C++ type system.
