// PreorderSeq returns an iterator that visits all the
// nodes of the files supplied to New in depth-first order.
// It visits each node n before n's children.
// The complete traversal sequence is determined by ast.Inspect.
//
// The types argument, if non-empty, enables type-based
// filtering of events: only nodes whose type matches an
// element of the types slice are included in the sequence.
