In Python 2.2+, you can usually avoid importing the 'types' module, and
just use the builtin constructors:

http://www.python.org/2.2.3/descrintro.html#factories

def nuke(lang):
    if isinstance(lang, tuple):    # instead of types.TupleType
        for oneLanguage in lang:
            nuke(oneLanguage)
    else:
        whatever
