This example xtend file generates code where the part 
"public Boolean apply(final ? e)" cannot be comiled:

------------------
import java.util.ArrayList
class Test {
	def <T> ArrayList<T> test(Iterable<T> iterable){
		var list = new ArrayList<T>()
		for(item:iterable){
			if(!list.exists(e|e==item)){
				list.add(item)
			}
		}
		list
	}	
}
------------------
generates to
------------------
import java.util.ArrayList;
import org.eclipse.xtext.xbase.lib.BooleanExtensions;
import org.eclipse.xtext.xbase.lib.Functions.Function1;
import org.eclipse.xtext.xbase.lib.IterableExtensions;
import org.eclipse.xtext.xbase.lib.ObjectExtensions;

@SuppressWarnings("all")
public class Test {
  
  public <T> ArrayList<T> test(final Iterable<T> iterable) {
    ArrayList<T> _xblockexpression = null;
    {
      ArrayList<T> _arrayList = new ArrayList<T>();
      ArrayList<T> list = _arrayList;
      for (T item : iterable) {
        final Function1<?,Boolean> _function = new Function1<?,Boolean>() {
            public Boolean apply(final ? e) {
              boolean _operator_equals = ObjectExtensions.operator_equals(e, item);
              return ((Boolean)_operator_equals);
            }
          };
        boolean _exists = IterableExtensions.<?>exists(list, _function);
        boolean _operator_not = BooleanExtensions.operator_not(_exists);
        if (_operator_not) {
          list.add(item);
        }
      }
      _xblockexpression = (list);
    }
    return _xblockexpression;
  }
}
