Hi,

import std;

will make everything available in the std namespace. However, there are
some features in the standard library that should not be used naïvely or
by novices.

Today, we limit the #include <iostream> to the TU that implements main()
as a means to prevent untestable functions relying on mutable globals
(std::cin/cout).

Will we have to rely on importing header modules instead of import std;
to get such a behavior of limiting dependencies?

Or would we have to use static analysis tooling to prevent the use of
undesirable features, which we now easily could grep for the
corresponding header #include?

Regards
Peter.
