comment:4 Changed 18 months ago by tscrim

What about making Cusps_class a subclass of sage.misc.fast_methods.Singleton?

comment:5 Changed 18 months ago by chapoton

What would be the benefit ?

EDIT: should I just replace UniqueRepresentation by Singleton ?

Singleton is faster (which probably means we can remove Cusps nailed in memory) and IMO makes the design more clear as it conveys some more semantics.

comment:7 follow-up: Changed 18 months ago by chapoton

Replacing UniqueRepresentation by Singleton does not work (conflict with Parent ?)

comment:8 in reply to: ↑ 7 Changed 18 months ago by tscrim

Replying to chapoton:

Replacing UniqueRepresentation by Singleton does not work (conflict with Parent ?)

What goes wrong? It shouldn't conflict with Parent, but it does have to come first because it needs to be at the bottom of the MRO (so there also cannot be any subclasses).

comment:10 Changed 18 months ago by chapoton

ok, thanks. I did put it in second position.

  • Reviewers set to Travis Scrimshaw

Thanks.

It probably should also use the Cusps.element_class instead of Cusp, but there is not any benefit right now (as nothing is really gained from the category). So that can wait for a followup if you want to just set a positive review now.
