Why Concepts didn’t make C++17
Even though I hardly use C++ nowadays, concepts and modules were two features I was looking forward to see in C++17, as a language geek.<p>However if it wasn&#x27;t for my goal to write portable native code across mobile OSes or the occasional weekend dive into LLVM, I would hardly touch C++ nowadays.<p>Waiting until C++20 for them, will mean 4 more years for alternatives to slowly erode C++&#x27;s usage where its features aren&#x27;t really that critical for fulfilling the customer&#x27;s use case.<p>On the other hand, people are still writing new Fortran code everyday, so maybe those 4 years won&#x27;t make a difference to those highly invested into C++.
