interception of put

[viktoras didziulis]

is there a way to intercept "put" command? For example there is a group 
"myGroup" having fields "F1" and "F2". What I would like to do is to put 
"something1" or "something2" into group "myGroup" and have script that 
would sort out "something1" going into field "F1" and "something2" into 
field "F2".

I could create a handler putIntoMyGroup "somethingX" and use it, but 
what I would like to do is to use simple "put" and to avoid adding any 
new function names, so that the group behaves like an independent object 
with properties of objects (fields, buttons, menus) that it holds and 
its script sorts out where all the set/get properties and put "things" 
are redirected to. Is it possible somehow to intercept a "put" into 
group "myGroup" with setProp/getProp control structure ?

And, what's more to this, is there a way to define group with new name 
so i could address group "myGroup" as myObject "myGroup"?

All the best :-)!
