c++.stlsoft - A use case for string_view

Here's what I think is an interesting use case for string_view:

<code>

class named_class
{
     string name const();
     // ... other properties
};

typedef std::map<string_view,named_class> container;

</code>

Replacing what could've been:
- map<string,named_class> duplicating name values
- vector<named_class> having to mantain element order manually
- vector<named_class> with linear searching

using the string_view, you can take advantage of map's functionality, 
without paying for duplicated name strings

Just a thought...

This is worth exploring (with mem-usage and speed tests)
