I consider somedict.get(x, x) a _frequent_ Python idiom!
translate_some_tags = dict(
def translate_tag(tagName, attributes_dict):
if tagName == 'emphasis' and attributes.get('role')=='bold':
return translate_some_tags.get(tagName, tagName)
Isn't that a pretty frequent idiom when doing some minor massaging of
XML markup, for example? (Spare me the passionate defenses of XSLT
please... I'm happy to use XSLT when warranted, but a lot of the XML
processing I do, and I _do_ do a lot of that, is in

A very good idea! If tomorrow you need to specialcase something, based
e.g. on RE's, you stick those into getstem (just like I do in
translate_tag for the few cases where a tag's translation may depend on
its attributes), and Bob's your uncle. MUCH better than spreading calls
to get(word,word) all over the place!!!
