Here's a good function header given the following:
I wrote the below code

    def showWarning(message, category, filename, lineno, file=None, line=None):
        assert isinstance(message, Warning)
        observeWarning(_Warning(str(message), category, filename, lineno))
    _setWarningRegistryToNone(sys.modules)
    origFilters = warnings.filters[:]
    origShow = warnings.showwarning
    warnings.simplefilter('always')
    try:
        warnings.showwarning = showWarning
        result = f(*args, **kwargs)
    finally:
        warnings.filters[:] = origFilters
        warnings.showwarning = origShow
    return result

What's a good function header?
