No, only python is special.  All other literals are aliens and shall not
be distinguished.  Just as with 'verbatim alien' and #verbatim.python#

It *does* matter to distinguish between verbatim python and verbatim
alien text, partly because we might want to (after the fashion of
doctest) verify that an alleged python verbatim *does* at least parse
and partly because the renderer may well wish to make some identifiers
in it be hyperlinks; whereas verbatim alien text should be simply echoed
(subject to stripping its indentation down to the level of its context,
naturally).
