As someone not very acquainted with C++ I was under the impression that the vast standard library was one of the great selling points of the language. What are

  The standard library is quite good, but is designed to be fairly general. Sometimes this means that you can do better with something you write yourself.

  depends where you come from. If you come from Python, Java, you'll find that there's a lack of support for networking, etc. and that it is not vast at all. After all we lack a W3CEndpointReferenceBuilder (https://docs.oracle.com/javase/10/docs/api/javax/xml/ws/wsaddressing/W3CEndpointReferenceBuilder.html https://docs.oracle.com/javase/10/docs/api/javax/xml/ws/wsad...).... not sure how it's possible to be productive without that. If you come from C you'll think that there are allocations everywhere and judge it unfit for purpose (even if in my experience, C libraries and software tend to allocate much more than C++, and use worse datastructures like linked lists, etc. just because it's easier to code in C). Finally the C++ committee and standard library implementers refuses to break ABI / API, which means that : * the C++ standard is not able to follow the state-of-the-art for e.g. hash maps, as the fastest hash maps (if you only care about speed of insertion / retrieval, which is let's be honest 99.5% of the use cases out there) because unordered_map has strict requirements that these newer hash maps do not satisfy. * things like regex stay broken
