I also received an additional note from Gustav Munkby, who reported the
bug.  He asked me to post it here:

================
It might however also be nice to document explicitly for the
Struct class that the built-in methods are overridden by the
accessor functions. If I use a Struct this is clearly what I
would expect, but to prevent others that want to iterate
over the Struct members for instance to perform the same
mistake.
================

Yours,
