StrictDict
----------
:class:`kitchen.collections.StrictDict` provides a dictionary that treats
:class:`str` and :class:`unicode` as distinct key values.

'''
Map class that considers :class:`unicode` and :class:`str` different keys
Ordinarily when you are dealing with a :class:`dict` keyed on strings you
want to have keys that have the same characters end up in the same bucket
even if one key is :class:`unicode` and the other is a byte :class:`str`.
The normal :class:`dict` type does this for :term:`ASCII` characters (but
not for anything outside of the :term:`ASCII` range.)
Sometimes, however, you want to keep the two string classes strictly
separate, for instance, if you're creating a single table that can map
from :class:`unicode` characters to :class:`str` characters and vice
versa. This class will help you do that by making all :class:`unicode`
keys evaluate to a different key than all :class:`str` keys.
.. seealso::
:class:`dict`
for documentation on this class's methods. This class implements
all the standard :class:`dict` methods. Its treatment of
:class:`unicode` and :class:`str` keys as separate is the only
difference.
