mutable string objects
Python strings are immutable objects. This has the advantage, that
strings may be used as dictionary keys. If this property isn't needed
and you insist on changing string values in place instead, you may cheat
and use MutableString.
But the purpose of this class is an educational one: to prevent
people from inventing their own mutable string class derived
from UserString and than forget thereby to remove (override) the
__hash__ method inherited from UserString. This would lead to
errors that would be very hard to track down.
A faster and better solution is to rewrite your program using lists.

- Metaclass for defining Abstract Base Classes (ABCs).
Use this metaclass to create an ABC. An ABC can be subclassed
directly, and then acts as a mix-in class. You can also register
unrelated concrete classes (even built-in classes) and unrelated
ABCs as 'virtual subclasses' -- these and their descendants will
be considered subclasses of the registering ABC by the built-in
issubclass() function, but the registering ABC won't show up in
their MRO (Method Resolution Order) nor will method
implementations defined by the registering ABC be callable (not
even via super()).
