Re: Next SWIG release

Hi,
	another way to reduce code size (which, I think, is also documented in the 
manual) is to replace:

    %typemap(in) Foo {
        // read $input (a PyObject*) and use the info in
        // order to build $1 (a Foo). Typically, the code
        // spans quite a few lines which are reinserted in
        // the wrappers every time a Foo is passed.
    }

with:

    %{
    void convertFoo(PyObject* input, Foo& f) {
        // put the conversion code here so that
        // it is only written once
    }
    %}

    %typemap(in) Foo {
        convertFoo($input,&$1);  // just one repeated line now
    }

I don't think it would be easy to have SWIG produce the above automatically 
(right, Dave?) but it can be done manually.

Bye,
        Luigi
