+## format directive
+
+Rather than making syntax highlight plugins have to provide a preprocessor
+directive as well as handling whole source files, perhaps a generic format
+directive could be used:
+
+	\[[!format pl """..."""]]
+
+That would run the text through the pl htmlizer, from the syntax hightligh
+plugin. OTOH, if "rst" were given, it would run the text through the rst
+htmlizer. So, more generic, allows mixing different types of markup on one
+page, as well as syntax highlighting. Does require specifying the type of
+format, instead of allowing it to be guessed (which some syntax highlighters
+can do). (This directive is now implemented..)
+
+Hmm, this would also allow comments inside source files to have mdwn
+embedded in them, without making the use of mdwn a special case, or needing
+to postprocess the syntax highlighter output to find comments.
+
+	/* \[[!format mdwn """
+
+	This is a comment in my C file. You can use mdwn in here.
+
+	"""]] */
+
+Note that this assumes that directives are expanded in source files.
