You can also use
%attribute_ref(class, type, pyattr, cppame);
%attribute_ref(class, type, refname, attr);
if the internal C++ reference methods have a different
name from the python attribute you want.

Then you can use the instances like:

x.b = 3 # calls A::b()
print x.b # calls A::b() const
NOTE: remember that if the type contains commas, such as
'std::pair<int,int>', you need to use the macro like:
%attribute_ref(A, SWIG_arg(std::pair<int,int>), pval);
where SWIG_arg() 'normalize' the type to be understood as a single
argument, otherwise the macro will get confused (see the 'cpp'
documentation).
