But groups have only one of those operators, and when it's written as + that usually means the group is commutative. So you wouldn't want + to denote sequence concatenation. If + and * are both present, that sounds like a ring, in which case you'd want "foo"*"bar" to work. It actually seems to me that exponentiation makes more sense than multiplication for turning "a" into "aaa". We think of aaa as what results from writing "a" with "3" in the superscript position. -- http://mail.python.org/mailman/listinfo/python-list
