Dear Sage developers,
Let me recycle this thread to report progress on the bookshelf of
standard object behavior. I just posted a small patch:
http://sagetrac.org/sage_trac/ticket/5120#comment:3
which implements sage.structure.UniqueRepresentation class. Derived
classes inherit a unique representation behavior for their instances.
Originates from sage.categories.category.uniq with:
- Long doc (6 pages for 12 lines of code)
- Default implementation of__eq__ and __hash__
- Handling of pickling in the simple cases
- Avoids multiple calls to __init__
- Enables rewritings of the constructor argument
This is a call for comments! (and reviews).
If the principle is validated, it could be worthwhile to use it quite
systematically for parents.
Best,
Nicolas
