Crash of code generator 2

[rocketnik]

The following code crashes when typing ivar in {% call convertType ivar %} - of course I was not finished typing. I wanted to type {% call convertType ivar.typeName %}, but code generation crashed as soon as ivar was entered - it is of the wrong type of course.

{% macro convertType typ %}{% typed typ as TypeName %}{% if typ.isDictionary %}IMap<{% call convertType typ.dictionary.keyTypeName %},{% call convertType typ.dictionary.valueTypeName %}>{% else %}{{ typ }}{% endif %}{% endmacro %}

<<<<<<<
{% for type in types.all %}
class {{ type.name }} {
    {% for ivar in type.variables %}
    final {% call convertType ivar.typeName %} _{{ ivar.name }};
    {% endfor %}
    {{ type.name }}({% for ivar in type.variables %}this._{{ ivar.name }}{% if not forloop.last %}, {% endif %}{% endfor %});
    {{ type.name }} copy({ {% for ivar in type.variables %}{% call convertType ivar %}{{ ivar.name }}{% if not forloop.last %}, {% endif %}{% endfor %}});
}
{% endfor %}

class Article {
  final String _title;

  Article(this._title, this._sections);
