This is usually called MA_STATE_INIT()

This is a bad iterator design. It's usually best to do this:
struct sample *sample;
SAMPLE_ITERATOR(si, min);
sample_iter_for_each(&si, sample, max) {
frob(mgr, sample);
}
I don't mind splitting apart MA_STATE_INIT from MA_STATE, and if you
do that, we can also use it in VMA_ITERATOR.
