extend behaviour of assignment operator

[avi.e.gross at gmail.com]

Guenther,

It is best not to suggest a drastic fix for a more limited problem.

As a general rule, many programming languages only have a pointer concept
even vaguely along the lines you want for garbage collection purposes. An
area of memory may have stored alongside it how many other things point at
it but not which ones. As long as it is decremented when a pointer leaves,
it works.

If you want to design objects that can store additional info when invoked
properly, go for it. No change to python would be needed. In your example,
you could create an object initialized by cube([10,1,1], "a") which now
might remember that something called "a" once pointed at it. But you then
have to figure out how to ensure than when "a" is deleted or reset or goes
out of the current environment, that things are properly updated.

I am not so sure how easy it would be to change the language so it pays
attention to what it is giving a pointer too and then goes and tells ...

Subject: extend behaviour of assignment operator

Hi,

when i run this code

a = cube([10,1,1])
b = a

i'd like to extend the behaviour  of the assignment operator
a shall not only contain the cube, but  the cube shall also know which
variable name it
was assigned to, lately. I'd like to use that for improved user interaction.

effective code should be:

a=cube([10,1,1])
a.name='a'

b=a
b.name='b' # i am aware that a.name also changes


can decorators also be used with assignment operators ?

thank you for your hints
