Yuck. -1 to compatibility with this. All or nothing -- if you're going to support double factorial, you should support any multifactorial. Reasonably, we can't expect to support arbitrary math input. We don't support |A| where len(A) does the job, and we don't accept half-open interval notation, either. I've made up my mind, I don't support the factorial notation. -1. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
