Extended STL (volume 1) Inventions: Introductions

As I've done for Imperfect C++, I'm going to enumerate the inventions (as opposed to techniques, or already established technologies) introduced in Extended STL (volume 1). Specifically, what are the (C++) programming components/techniques/technologies that I invented that are documented in the book.

I will make a series of posts covering the inventions, including:

• element reference categories, including the By-Value Temporary Reference
• Argument-dependent Return-type Variance (ARV)
• External Iterator Invalidation
  
• examination of the separation of Reversibilitty and Bidirectionality
• UNIXSTL's glob_sequence
• UNIXSTL's readdir_sequence
• InetSTL's findfile_sequence
• InetSTL's ftpdir_sequence
• WinSTL's findfile_sequence
• WinSTL's listbox_sequence and combobox_sequence
• WinSTL's pid_sequence
• WinSTL's process_module_sequence
• MFCSTL's CArray_cadaptor
  
• MFCSTL's CArray_iadaptor
  
• WinSTL's child_window_sequence
• WinSTL's zorder_iterator
• PlatformSTL's environment_map
• STLSoft's string_tokeniser
• COMSTL's enumerator_sequence
• COMSTL's collection_sequence
  
• ACESTL's message_queue_sequence
  
• STLSoft's ostream_iterator
• STLSoft's cstring_concatenator_iterator
  
• STLSoft's string_concatenator_iterator
• STLSoft's member_selector_iterator
• STLSoft's adapted_iterator_traits
• STLSoft's filter_iterator
  
• STLSoft's transform_iterator

Over time, I'll post short examples/explanations regarding each of these.
