What the hell? Oh yeah, you must be using pike again. No, if it were pike the list would look like this: ({({"q"}), ({"w","e"}), ({"r","t","u"}), ({"i","o","p"})}) Of course you'd have to declare it first using an /expanded/ Java syntax: nested_list = array(array(string)) Folks, i couldn't make this stuff up if i wanted to. Go read for yourself if want a few laughs. http://pike.lysator.liu.se/docs/tutorial/data_types/container_types.xml > I'm not sure what your definition of a numeric type is, but I suspect > that list(str) isn't part of it.
