C++20 Reference Card
Whenever I see new C++ features I&#x27;m all the more impressed with how Zig manages to provide capabilities similar to -- and at least as powerful as -- type templates, value templates, constexprs, concepts, and conditional compilation (preprocessor), with a single feature and keyword, without any type&#x2F;template-level programming, a preprocessor or AST macros (i.e. mini-languages different from the ordinary computation language that one has to learn and can make code quite opaque), all in a language that is about as simple as C and can be fully learned in a day or two.
