 The string_view has the following constructor:

 {{{#!cpp
 BOOST_CONSTEXPR basic_string_view(const charT* str)
         : ptr_(str), len_(traits::length(str)) {}
 }}}

 This uses a 'length' call to determine its length. It would be nice if it
 could differentiate between compile time array's and other strings.
 However others have failed as well:
