[issue8639] Allow callable objects in inspect.getargspec

[Marco Mariani]

I second this, I depend on this monkeypatch for my turbogears projects, where I use callable objects as error handlers:

    def getargspec(func):
        if getattr(func, '__call__') and not isfunction(func) and not ismethod(func):
            func = func.__call__
        if ismethod(func):
            func = func.im_func
        if not isfunction(func):
            raise TypeError('arg is not a Python function')
        args, varargs, varkw = getargs(func.func_code)
        return args, varargs, varkw, func.func_defaults

but I suppose 2.7 is locked to this change so I propose it for 3.x
