Hi,
Is there an easy way of duplication IDL objects (not their
references)? You can off course make a new object with obj_new and use
set/getproperty to transfer all properties, but that's a bit silly no?
Thx,
Wout

The SAVE/RESTORE mechanism isn't always too slow. I use it every time
I print a graphics object.
Be aware that copying an object is non-trivial. What do you do with
references to other objects: copy the reference or copy the object?
The former is, I think, called a shallow copy and the latter is called
a deep copy. There are pitfalls in either case.
But didn't some guy called Coyote write an article about copying
objects?

Spam'em. Use all 10000 of your aliases or we don't have a chance. :-(
Cheers,
