IMHO, an expression like 1 + [2,3,4,5] is utterly confusing. Among all the possible meanings it could have, [3,4,5,6] is the last that comes to mind; if SAGE started to use such a syntax, you'd hear me and i think many other users on this forum asking for a way to disable the mechanism. Just a thought : x + [a, b, c] and [a,b,c] + x should both be [x+a, x +b, x+c] ? but that's not even commutative, ergo impossible : [1] + [12, 13] should be [ 1 + [12,13] ] = [ [13,14] ] but it should also be [ [1] + 12, [1] + 13] = [[13], [14]] and that ain't the same. You could reply that the syntax should only apply to "numbers", but that would be re-inventing the idea of the "vector" class, and i thought re-inventing the wheel was against sage's philosophy. On the other hand, [ 1 + x for x in [2,3,4,5]] appeals to both mathematicians and geeks. yours, Pierre --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
