Support `__getattr__` method in AC
I tried to convert the function to Argument Clinic, but it failed, oh!
Error in file 'Modules/zlibmodule.c' on line 2019:
'__getattr__' is a special method and cannot be converted to Argument Clinic!

Would this be a valid feature request for AC or it’s somehow impossible?
