Mixins and initialize/initialize_copy

[Rüdiger Sonderfeld]

Hello,
I have created a mixin module that overwrites initialize and initialize_copy.
This works fine until a class that uses the mixin wants to overwrite initialize
and/or initialize_copy, too.

I can replace initialize with lazy accessors. But I don't know how to handle
initialize_copy:

The mixin manages some attributes and the initialize_copy method makes sure
that cloning the object clones the managed attributes.

What would be the best solution to this problem?

Regards,

Anyone who does this kind of thing should always check to see if the
method is already defined and if it is wrap it --NEVER just overwrite
these instrumental methods.

Calling super from the instance methods of your class?
