 afaik, no. it's just a regular exported function that would look 
something like this in Erlang.

module_info() -> <list of tagged tuples>.
module_info(Tag) ->
 try proplists:get_value(Tag,module_info())
 catch _:_ -> exit(badarg)
 end.

 where <list of tagged tuples> is a constant term.
 this is just speculation on my part though.
