## +23 ## Regular, Revisited ## V ICTOR CIURA ## 20 23 October 01 - 06 ## Abstract “Regular” is not exactly a new concept. If we reflect back on STL and its design principles, as best described by see that regular types naturally appear as necessary foundational concepts in programming. Why do we need to bother with such taxonomies? Because STL assumes such properties about the types it deals with structures and algorithms to work properly. STL vocabulary types such as string_view, span, optional, expected etc., raise new questions regarding values types, whole-part semantics, copies, composite objects,

## Back to Basics: Algebraic Data Types I also do C++ training! arthur.j.odwyer@gmail.com ## Outline - Why the name “algebraic data types”? [3–18] o Memory layout diagrams. Why not std::any? • Quick [50–56] Questions? • More about pair and tuple [57–69] Questions? ## What do I mean by algebraic types? pair C++98. The original algebraic data type. tuple C++11. optional C++17. variant C++17 possible values| ## Pair and tuple are product types To find the size of the domain of a pair or tuple type, we take the product of the sizes of its element types. |A|A possible values| |---|---| |pair<A

For example, in Haskell, the following are types, representing integers, characters, lists of characters, and lists inhabitants of those types: • 42, 'a', Hello world!, [2, 3, 4, 5, 6] In a language with dependent types, however, the distinction is less clear. Dependent types allow types to “depend” on values

## BEN DEANE / @ben_deane CPPCON 2021 ## I N THIS TALK 1. Composability defined 2. Composable types 3. Objects and patterns 4. Composability at compile time 5. Hierarchies and computation ## COMPOSABLE _composably() -> int; Spoiler: bool and int are in some sense the only two composable return types we need... ## WHY int? Of course, int can represent N (32?) bools, using bitand (&) and bitor COMPOSABILITY FROM PRINCIPLES At the core, steering behaviours is based on the composability of arithmetic types. A single function returns a force that can be accumulated and applied. The resulting framework
