Comment:

 All the variations of `basic_string_view::compare` are marked as
 constexpr. (well, `BOOST_CXX14_CONSTEXPR`).
 But, as you correctly point out, the operators (`< <= == != > > =` are
 not.

 > However, constexpr compare() in Boost never works in C++14, since it
 uses std::char_traits in standard library.
 That's not strictly true; merely a default. You are free to use your own
 traits class.

 I'll fix the operators.
