[C++-sig] How to add an __init__ function ?

I want to add an init function which is not a contructor of the original 
class. I export a C++ container and I want to be able to import any 
sequence object, so I created a (working) function 
"from_list(Container*, boost::pyhon::object obj)" which iterates over 
every elements of obj if an iterator can be created. But, if I define 
the '__init__' function with:

   .def ("__init__", from_list)

And I try this in python:

 >>> Container([1,2,3])

I get the error:
Boost.Python.ArgumentError: Python argument types in
   Container.__init__(Container, list)
did not match C++ signature:
   __init__(Container*, boost::python::api::object)

It seems to me that the second __init__ method just should be ok ...
