Complex type specification in documentation.

Hi, could you please describe how I can specify complex types in doc strings. For instance I found that I could write following for:

class C:

     @classmethod

     def c(cls):

          pass

     def m(self):

          pass

var1 = None

"""

:type : list of C

"""

var1[0]. #<-complete here with members of C

var2 = None

"""

:type : dict from string to C

"""

var2["a"]. #<-complete here with members of C

But the same doesnt work for set or deque.

Also i dont know how to write someting like this:

def f():

     """

     :rtype : iterable of C

     """

     for i in xrange(10):

          yield C()

to have autocomleation in loops:

for g in f()

     g. #<-complete here with members of C

Also i dont know how to specify following:

var3 = None

"""

:type : tuple of int, string, list of C

"""

var3[0]. #<-compleate here with members of int

var3[1]. #<-compleate here with members of string

var3[2]. #<-compleate here with members of list

var3[2][0] #<-compleate here with members of C

Also i want to know how to describe class type:

var4 = None

"""

:type : class of C

"""

var4. #<-compleate here with members of C.__class__

var4.c() #No warn here

var4.m() #<-Warn here for missing argument

var4.m(var1[0]) #No warn here

var4(). #<-compleate here with members of C

thanks in advance.
