On the face of it, it's incorrect, because you can append any sort of object to a list, right? This message appears in the list_concat method. Shouldn't it be something like can't concatenate \"%.200s\" object with list ? I would consider this change very picky except for the fact that it's making a statement about the properties of lists that is clearly not true. -- Skip Montanaro, skip@mojam.com, http://www.mojam.com/, http://www.musi-cal.com/ "We have become ... the stewards of life's continuity on earth.
