Another issue is that we *already* have a name for "finite rank free ZZ-module with inner product", namely "FreeModule". This has been in Sage for years. sage: L = FreeModule(ZZ,2,inner_product_matrix=[[1,2],[2,4]]) sage: L.0.inner_product(L.1) 2 Choosing the names for the global namespace is a very important responsibility, and each choice should be taken with a lot of taste and care. It really does matter a great deal. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
