So you're suggesting to start with implementing a new primitive instead of
a byte code instruction, aren't you?  That's a good idea, because it
doesn't affect the Parser/Decompiler/Debugger/whatever.  I could use
something like

  delegate: #thisSelector
  to: theObjectWhereTheLookupStarts
  withArguments: anArrayOrNil

to test my ideas -- and IT WORKS!  It's actually very simple.  All I needed
to do was to clone and slightly modify the #perform:withArgument:
primitive.  I've prepared a patch file, which will be available on my
Squeak Page at tomorrow.

That's of course the next step then. Yes.

I think, I'll wait for the next version of Jitter before I'll have a look
at that class.  All I want is to satisfy my curiosity :-)
