Any interest in a filename (parser) class?

Hello,

Is there any interest in a filename parser library?

What I have in mind is a filename class modelled as a container of 
path components; each path component consists of a "proper" name and 
an extension, something along these lines:

// (possibly a template)
class filename_component
{
public:
  typedef std::string string_type;

  // Full name
  string_type str() const;
  void str( const string_type &s );

  // Name minus extension
  string_type proper() const;
  void proper( const string_type &s );

  // Extension
  string_type ext() const;
  void ext( const string_type &s );
  bool has_ext() const;

  // ...
};

// This is a sequence of filename_components
class filename
{
public:
  // Things from sequence requirements, e.g.
  const filename_component & 
    operator [] ( size_type n ) const;

  //
  // additional members
  //

  static const char path_sep_char;

  // Full path name
  string_type str() const;
  void str( const string_type &s );

  // Parent filename
  filename parent() const;

  // Absolute or relative path?
  bool absolute() const;

  // Last component
  const filename_component &base() const
  {
    return operator[] ( size() - 1 );
  }

  // ...
};

Comments?
