Good stuff. Where i differ on everyone i know is in inheritance and
descendants. I wish to allow full overloading and multiple inheritances, li=
ke:

<not any code in particular>
class a = bird
  properties = { }
  methods ____
class b = mammal
  properties = { }
  methods ___

class platypus ==20
   inherit class a
   inherit class b -- last inherit has priority
   properties = { } -- overload as necessary
   methods ____ -- overload as necessary

</code>

Also, dynamic changes in methods and any data field while the program is=

running, with changes (or additions or deletions) propagated thru all
descendants instantly.
