Dave Malcolm <dmalcolm at redhat.com> added the comment:
Another optimization idea: detect local dictionaries that are only ever used in non-mutating ways, and convert them to constants, rather than rebuilding the dict from scratch each time.
See e.g. htmlparser.py:adjustSVGAttributes etc within the bm_html5lib benchmark (though this doesn't seem to be ported to py3k yet)
