The hack I used was to ensure that there was a framemenu/iconmenu class
variable in the same dictionary as the createframemenu/createiconmenu
procedures.  For obvious reasons this hack is easily fooled;  however
these problems didn't come up for me.  Creating those menus adds nearly
a second (half the time) to creating a window (the other big consumer is
in allocating the canvas itself).

I also have a version of class.ps which you should be able to get from
SUN, which allows multiple inheritance, class re-definition, adding new
methods and class variables after class definition, and type/inheritance
checking.

Finally there is also an inspector I wrote for NeWS structured objects
(dictionaries, arrays, processes etc.) which shows all the key/value pairs
in these things and allows you to update them.  There was a bug in updating
executable arrays last time I looked.

*I no longer work at Schlumberger, where I wrote these.  SUN has
re-distribution rights for them;  ask there or at Schlumberger.*
