I meant extension in sence that it's a LaTeX language extension to it's superset.

There's no LaTeX package and I myself will not port it. SugarTeX is Pandoc/Markdown oriented project in the first place.

You can use it as a command line prepocess text filter though. It should work as long as you use ˎ or ˎˎ to define SugarTeX.
