Wrong guess: http://language-binding.net/pygccxml/apidocs/pygccxml.declarations.declaration.declaration_t-class.html#partial_name

By the way, container_traits has "remove_defaults" functionality. Now,
you know what it is for.

This is a must functionality for a good code generator - the generated
code should be as closed to "human written" as possible.
