Octave 4.0+ and WAFO

[jmb]

In the URL http://www.maths.lth.se/matstat/wafo/faq.html

It states:

Does WAFO work on Octave?
WAFO is not written to be compatible with Octave
(http://www.gnu.org/software/octave/) and at present many functions does
not work with Octave. However, from release 2008, WAFO will use function
handles and custom classes which are not compatible with Octave version
2.9.14. Hopefully in the future Octave will support nested functions and
custom classes so that WAFO can be made compatible with it.

I have installed:
        octave --version
        GNU Octave, version 4.0.0

Does this version support?
        A) function handles
        B) custom classes

I read:
https://lists.gnu.org/archive/html/help-octave/2015-02/msg00007.html
where Rik states:
        "Support for the @class syntax has been available in Octave for
a long time.  Upgrade to the latest stable release and then use the same
syntax as Matlab."

and:
https://www.gnu.org/software/octave/doc/v4.0.1/Function-Handles.html

https://www.gnu.org/software/octave/doc/v4.0.0/Function-Handles.html#Function-Handles
where @function-name is documented

So it appears that these two features are supported.  So has anybody had
success making WAFO work with Octave 4.0.0?
