[squeak-dev] modifying instance variable allocation

Hi list,

I'm trying to make an object that has special instance variable
allocation methods by overriding #instVarAt: and #instVarAt:put:, but it
isn't working.

In an inspector, the fields are presented as expected, but the
#pushRcvr: and #popIntoRcvr: bytecodes seem to use the basic behavior.

#instVarAt: and #instVarAt:put: aren't labeled 'No lookup.' like #== is,
but the VM bytecode evaluator doesn't use them for instance variable
access so the overridden the new behavior only works in the simulator...
which includes everything from inspectors to fileIn/Out and bytecode

Is this something you can do? or are you required to use custom getter
and setter methods?
