Mathias HasselmannI am pretty sure you all already know, but it's actually possible to have `requires` clauses at the end of a function declaration. Just like any other attribute.This makes usage of ad-hoc requirements much more readable and greatly reduces the pressure to introduce custom concepts.Why are so many teaching the front syntax instead of the tail syntax?<a href="https://mastodon.green/tags/Concepts" class="mention hashtag" rel="nofollow noopener" target="_blank">#Concepts</a> <a href="https://mastodon.green/tags/CPP" class="mention hashtag" rel="nofollow noopener" target="_blank">#CPP</a> <a href="https://mastodon.green/tags/CPP20" class="mention hashtag" rel="nofollow noopener" target="_blank">#CPP20</a> <a href="https://mastodon.green/tags/ModernCPP" class="mention hashtag" rel="nofollow noopener" target="_blank">#ModernCPP</a> <a href="https://mastodon.green/tags/Programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#Programming</a>

Andreas FertigWhy do C++ templates confuse so many developers? Because the syntax is tricky, the errors are cryptic, and most tutorials don’t explain the why behind the how. In my self-paced course, we fix that. Step by step, you’ll see how templates work, so you can write efficient, reusable code with confidence. Join now and start mastering!And yes, you’ll also get a complimentary copy of my "Tips and Tricks with Templates" book when you book before April 30th.<a href="https://mas.to/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a> <a href="https://mas.to/tags/cpptemplates" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpptemplates</a> <a href="https://mas.to/tags/ModernCpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#ModernCpp</a>

Sean MurthyI won't be the first to say this, but we need to retire the phrase "Modern C++". I mean, C++11 was 12 years ago. I understand that branding was necessary back then due to significant changes in the language and library, but it is ridiculous to continue to cleave language versions like that.For my part, I just removed "Modern" from a course title, and I'm not looking back. 🚀 <a href="https://hachyderm.io/tags/cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpp</a> <a href="https://hachyderm.io/tags/cplusplus" class="mention hashtag" rel="nofollow noopener" target="_blank">#cplusplus</a> <a href="https://hachyderm.io/tags/modernCpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#modernCpp</a>
