No, any operation can report TypeError and ValueError without explicit
mentioning in the documentation. Saying that the parameters should be
this and that implies that if they are different, you get a TypeError
or ValueError.

See my example again:

py> locale.setlocale(locale.LC_ALL,u"en")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/locale.py", line 513, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
py> locale.setlocale(locale.LC_ALL,u"eng")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/locale.py", line 512, in setlocale
    locale = normalize(_build_localename(locale))
  File "/usr/lib/python2.6/locale.py", line 420, in _build_localename
    language, encoding = localetuple
ValueError: too many values to unpack

So for u"eng" you get the ValueError. For u"en", you get past that
point, and then get a locale.Error. These are both Unicode strings,
but the outcome is quite different (and still would be different
under your patch).
