<p><tt class="xref py py-class docutils literal"><span class="pre">kitchen.collections.StrictDict</span></tt> provides a dictionary that treats
<tt class="xref py py-class docutils literal"><span class="pre">str</span></tt> and <tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt> as distinct key values.</p>

<dd><p>Map class that considers <tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt> and <tt class="xref py py-class docutils literal"><span class="pre">str</span></tt> different keys</p>
<p>Ordinarily when you are dealing with a <a class="reference external" href="http://docs.python.org/library/stdtypes.html#dict" title="(in Python v2.7)"><tt class="xref py py-class docutils literal"><span class="pre">dict</span></tt></a> keyed on strings you
want to have keys that have the same characters end up in the same bucket
even if one key is <tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt> and the other is a byte <tt class="xref py py-class docutils literal"><span class="pre">str</span></tt>.
The normal <a class="reference external" href="http://docs.python.org/library/stdtypes.html#dict" title="(in Python v2.7)"><tt class="xref py py-class docutils literal"><span class="pre">dict</span></tt></a> type does this for <a class="reference internal" href="glossary.html#term-ascii"><em class="xref std std-term">ASCII</em></a> characters (but
not for anything outside of the <a class="reference internal" href="glossary.html#term-ascii"><em class="xref std std-term">ASCII</em></a> range.)</p>
<p>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 <tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt> characters to <tt class="xref py py-class docutils literal"><span class="pre">str</span></tt> characters and vice
versa. This class will help you do that by making all <tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt>
keys evaluate to a different key than all <tt class="xref py py-class docutils literal"><span class="pre">str</span></tt> keys.</p>

for documentation on this class’s methods. This class implements
all the standard <a class="reference external" href="http://docs.python.org/library/stdtypes.html#dict" title="(in Python v2.7)"><tt class="xref py py-class docutils literal"><span class="pre">dict</span></tt></a> methods. Its treatment of
<tt class="xref py py-class docutils literal"><span class="pre">unicode</span></tt> and <tt class="xref py py-class docutils literal"><span class="pre">str</span></tt> keys as separate is the only
difference.</p>
