What's new in C++17?

C++17 in details: Templates

by Bartlomiej Filipek

From the article:

Do you work a lot with templates and meta-programming?
With C++17 we get a few nice improvements: some are quite small, but also there are notable features as well! All in all, the additions should significantly improve writing template code.

Today I wrote about:

• Template argument deduction for class templates
• template<auto>
• Fold expressions
• constexpr if
• Plus some smaller, detailed improvements/fixes

BTW: if you’re really brave you can still use concepts! They are merged into GCC so you can play with them even before they are finally published.
