The C++ standard library, also known as the STL, is a remarkable achievement with broad scope, performance, and backward compatibility. While hailed for its merits, criticisms include abysmal compile times and unreadability. However, using the STL is optional, and developers can create their custom standard library. A unique approach, pystd, replicates Python’s stdlib design. The library enables users to read, validates, and manipulate text files efficiently. By disabling the STL, users can build a streamlined, efficient alternative with fewer lines of code than the traditional STL. The new library ensures ABI stability through innovative namespace and versioning techniques.
