Detailed Description

C_str for char const*; Wide_c_str for wchar_t const*; and Mutable_c_str and Mutable_wide_c_str as ditto mutable types.

The shortest names like C_str stand for const string data. The prefix Mutable_, as in Mutable_c_str, indicates mutable string data. This naming reflects an experience that handling const string data is by far most common.

Using the type names avoids issues with non-reading direction placement of *, and it supports prefix const. For example, instead of

char const* const s = "Blah";

... you can write

const C_str s = "Blah";

Of course, for this particular example it would be silly to throw away the string length information, so one should better use std::string_view and write

constexpr string_view s = "Blah";
