Standard Vocabulary for Algorithms

This is feedback after considering A Plan for C++23 Ranges Disclosure: I voted in favor of this. It does not suggest work on views::maybe [P1255R6]‚Äč. I’m fine with that priority. Vocabulary is not just Types between Components There’s broad agreement that ‘vocabulary types’ belong in the standard. Domain independent types that can be used between […]

Building Saar Raz’s clang concepts branch

A Recipe for building Saar Raz’s clang concepts branch Saar Raz has been working on a Concepts implementation, available at https://github.com/saarraz/clang-concepts It’s not much harder to build it than clang usually is, it’s just a matter of getting things checked out into the right places before configuring the build. Just like LLVM and clang normally. […]

Should Unicode literals be guaranteed to be well-formed?

TL;DR Betteridge’s law applies: No. Are you still here? Unicode Literals In C++ 20 there are 2 kinds and 6 forms of Unicode literals. Character literals and string literals, in UTF-8, UTF-16, and UTF-32 encodings. Each of them uses a distinct char type to signal in the type system what the encoding is for the […]

Why std::bind can’t be (formally) deprecated

Yes: std::bind should be replaced by lambda For almost all cases, std::bind should be replaced by a lambda expression. It’s idiomatic, and results in better code. There is almost no reason post C++11 to use std::bind. Doing so is quite straightforward, capture each bind argument by value in the lambda capture list, and provide auto […]
