[Ironpython-users] How to use __ getattr__ to the current module?

[sepatan at sibmail.com]

Hello, Dino Viehland ).
Thank you for your participation. In your example foo is required.
It works:
class met(type):
    def __getattr__(cls, t):
        <here is the code>
    def __call__(cls, *args, **kw):
        <here is the code>

class cl(object):
    __metaclass__=met
        <here is the code>

cl(6,y=7).tt(3,yy=4) (and so on)

but cl required.
And must be so:
tt(3,yy=4) (and so on)
--------------------------------------------------
1)Tried this:
import types
class cl_mod(types.ModuleType):
    def __getattr__(self, *args, **kw):
        <here is the code>

sys.modules.setdefault('ppp', cl_mod('ppp'))
import ppp #(or from ppp import *)
tt(3,yy=4) (and so on)
does not work ((. In __getattr__ does not go.

2)and so:
class cl_mod(object):
    def __getattr__(self, *args, **kw):
        <here is the code>

sys.modules[__name__]=cl_mod()
tt(3,yy=4) (and so on)
does not work ((. In __getattr__ does not go.

Until all Waterloo (. But, I think that I will overcome).
