A.  I *think* you meant
        import re
        from htmlentitydefs import name2codepoint
        def htmlentitydecode(s):
            return re.sub('&(%s);' % '|'.join(name2codepoint), lambda m: chr(name2codepoint[m.group(1)]), s)
    We're stretching the limits of what's comfortable
    for me as a one-liner.
B.  How's it happen this isn't in the Cookbook?  I'm
    curious about what other Pythoneers think:  is 
    this better memorialized in the Cookbook or the
    Wiki?
