The help(obj) function uses the type of obj to create its result.  This is less than helpful when requesting help on a wrapped object.  Since 3.5, inspect.signature() and inspect.from_callable() have a follow_wrapped option to get around similar issues.  Adding the option to help() would prevent surprising behavior while still allowing current behavior to be used when needed.  See http://stackoverflow.com/a/17705456/603136 for more.
