We'd need to do serious *extra* work and checking for that. Currently, if MatrixSpace(R,n,m)(L) works then matrix(R,n,m,L) will work too. Making sure that matrix(R,n,m,L) breaks for some L where MatrixSpace succeeds would require extra testing and explicit error raising. Would that really be an improvement? To ensure that the following happens? sage: matrix(2,2,x+y) [0 1] [1 2] (assuming x+y would be recognized as callable before it is recognized as iterable)? I think the current answer is less surprising. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
