 This section is about proxy objects that are in <code>boost::assign::detail::auto_size</code>. The functions
 that return them, however, ref_list_of(), ref_csv()
 and their variants, operate under the same principle as those in the rest of this library and are therefore in namespace <code>boost::assign</code>.
- In this framework, nested compile time expressions are formed from references to passed argument, and fitted, as needed, with iterators and
- conversion operations. This is in contrast to other parts of this library, where a passed argument is either directly inserted into its destination
- container or stored in a runtime-fashion.
+ Compile time expressions are formed from references to passed argument, which frees the user from the need to specify the
+ size of the collection explicitly.
