I was just reading the PEP, and caught this bit:
"Does OrderedDict.popitem() return a particular key/value pair?
Yes. It pops-off the most recently inserted new key and its
corresponding value."
Okay, but I'd also like a convenient and fast way to find the oldest
key, which I think I'd need for an LRU cache. I didn't notice one in
the patch. Perhaps I simply missed something. Shouldn't popitem()
allow the caller to choose which end from which to pop?
