>From a python's user point of view. a sorted dict/set/list was sometimes a requirement for me. Basically. a dictionary that had a BTree implementation instead of a hash table. Also. having an explicit type error would then be a clear indication that you have something wrong in your implementattion (and therefore useful indication).
<br>Other languages have separate collection frameworks like C# has powercollections. Having these collections as part of the standard library is another issue though.<br><div><span class="gmail_quote">On 9/15/07, <b class="gmail_sendername">

</div><br></span>It doesn't make sense for Python to have sorteddict or
sortedset. You see, dict can have keys which cannot be
ordered (keys can be heterogeneous, in which case Py3K may raise TypeError; ordering doesn't make sense for the objects used as keys) and
same goes for set elements.<br>
<br>
Sorting makes sense only as a run-time operation, in which case, the programmer should be prepared to handle appropriate exceptions.<br clear="all"><br>Btw, would you like a dict or set for which you have to handle exceptions at every insertion?
