Gettin all together, we want:
cdef extern from "foo.h":
cclass Foo: # or whatever else we come up with here
Foo __add__(Foo, Foo)
Foo __add__(Foo, int)
int __dereference__(Foo)
Foo __increment__(Foo) #different of inc(), right?
cpp_Iterator __iter__() #or something like this
foo = Foo()
for inc() and dec(), there are many ways to do it;
it = foo.begin()
it = get_begin_iterator(foo) #or cython.get_begin_iterator(foo)
with types:
cdef cpp_Iterator it = foo.begin()
...
and to use in() and dec():
cython.inc(it)
foo.inc(it) #this way, it's possible to customize your own inc() and dec()
it.inc()
we just need to find the better way to use these functions/methods.
I think it would be the same for deref (only on syntax, no custom
implementation)
