"""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."""
