Unlike everything is standardized in current C++, are there any specific reasons to leave int, char, ...., main() and others from it. (Not talking of +,-,%,.. because they aren't language-specific)
Why is it not like:
std::int std::main(std::int argc, std::char *argv[])
{
//Sample C++ code (incorrect with current standards though)
std::return 0;
}
Isn't standardization incomplete with them out of std scope?
What I believe is, they are basic components which occurs everywhere when writing a program, whether simple or complex. They are not included in the standardization, just to follow the DRY principle.
Keywords such as int and return and the main() function are all included in the C++ standard. std does not mean that only those things are standardized. Instead, it refers to the things that are in the standard library (which, like keywords, is a part of the standard). Include files such as #include <vector> are needed to use the standard library, but keywords can be used without any #includes.
