[134] Fix | Delete
Python strings are immutable objects. This has the advantage, that
[135] Fix | Delete
strings may be used as dictionary keys. If this property isn't needed
[136] Fix | Delete
and you insist on changing string values in place instead, you may cheat
[137] Fix | Delete
and use MutableString.
[138] Fix | Delete
[139] Fix | Delete
But the purpose of this class is an educational one: to prevent
[140] Fix | Delete
people from inventing their own mutable string class derived
[141] Fix | Delete
from UserString and than forget thereby to remove (override) the
[142] Fix | Delete
__hash__ method inherited from UserString. This would lead to
[143] Fix | Delete
errors that would be very hard to track down.
