Apologies that this bug is meta. I'm using "package:analyzer_experimental". So the analyzer is analyzing itself... :)

additional info, chasing now the type hierarchy shows that NodeList does (eventually) implement Iterable<VariableDeclaration>:

    class NodeList<E extends ASTNode> extends ListWrapper<E> { ... }
    class ListWrapper<E> extends ListBase<E> implements List<E> { ... }
    typedef ListBase<E> = Object with ListMixin<E>;
    abstract class ListMixin<E> implements List<E> { ... }
    abstract class List<E> implements Iterable<E> { ... }

might be be something with generics?

hmmm, here's another strange case:

  for (int i = 0; i < fields.variables.length; i++) {
    final field = fields.variables[i];
    final name = field.name.name;

field is inferred (black color) and has completions. field.name.name also works (hover shows "String get name"). But "name" is purple and doesn't complete.
