Comment:

 As you note, we've been down this rathole before.
 You can pass pointer and length; there's a constructor for that.

 And then there's the whole "trailing null" issue:

 {{{
 const char arr1 [] = { 'H', 'e', 'l', 'l', 'o' };
 const char arr2 [] = "Hello";
 const char p1 = "Hello";
 }}}

 If you make a `string_view` from `arr1`, its `size()` should be five,
 because there are five characters in the array.

 If you make a `string_view` from `p1`, its `size()` should be five,
 because that's what `traits::length` returns.

 What about `arr2`?   Should it be 6, since there are six characters in the
 array? Or 5, since the last character is a NUL?
