+    The actual implementation of :ttag:`{% comment %}<comment>` is slightly

+    ``{% comment %}`` and ``{% endcomment %}``. It does so by calling

+    followed by ``parser.delete_first_token()``, thus avoiding the generation of a
+    node list.

 ``parser.parse()`` takes a tuple of names of block tags ''to parse until''. It
 returns an instance of ``django.template.NodeList``, which is a list of
 all ``Node`` objects that the parser encountered ''before'' it encountered
