What's a "*.init" method? Do you mean SomeType.__init__() ?

You might want to take a look at Cython. It allows you to write C
extensions in a Python-like language, so all of the above become trivial, e.g.
cdef class MyExtensionType(object):
def __init__(self, bint some_c_bool):
print type(self) is MyExtensionType
print some_c_bool == 1
Cython will translate this to efficient C code for you.
