I doubt that something like that exists.  Note that Erlang is not just a 
higher-order language where you need to do a complicated analysis, but 
it is also language that also allows something along the lines of:

   % foo/3 is an exported function (called with some constructed lists)

   foo(L1, L2, Args) ->
     M = list_to_atom(L1), F = list_to_atom(L2), apply(M, F, Args).

Of course, writing an analysis that is effective if no such cases exist 
or a conservative analysis that protects itself from such cases is 
doable.  But you need to base it on a "closed-world assumption" of some
