Making C++ easier to teach can overlap with making it easier to use for
professional developers. For example, part of the motivation for P1679 was
to make C++ easier to teach, though it will also make the language more
pleasant to use for experienced developers.

Before P1679:
    if (haystack.find("needle") != std::string::npos)

With C++23:
    if (haystack.contains("needle"))

C++20 also added .contains() to containers and starts_with()/ends_with() to
strings. Making C++ more natural to read lets developers focus more on the
task being solved than the language details.
