The ! And ? Characters in a name are not decorators, they are
significant.  This is what allows us to have both File.open() and
File.open?().

Python was forced to have file.closed().  Not only is it harder to tell
which is a command and which is a question in Python, but you have the
illogical negative-based question in Python.
