The Range class allows most values to be used as endpoints, even things such as type objects. But certain type objects get mistaken for defined objects, causing silly error results: > Range.new(List, Pair).perl List..Pair > Range.new(Seq, List).perl Seq objects are not valid endpoints for Ranges in block <unit> at <unknown file> line 1 > Range.new(List, Int).perl List..Int > Range.new(Int, List).perl Use of uninitialized value of type List in numeric context in block <unit> at <unknown file> line 1 Use of uninitialized value of type List in numeric context in block <unit> at <unknown file> line 1 Invocant requires an instance of type Int, but a type object was passed. Did you forget a .new? in block <unit> at <unknown file> line 1 These type objects should be either successfully allowed or cleanly prohibited. They don't have the disadvantages that the corresponding defined objects would have, so they should probably be allowed. -zefram
