Getting to know who peer reviews a Sci-Writing assignment

peerReview.erl

-module(peer).
-export ([draw/0]).

draw()->
    R = random:uniform(100),
    io:format ("~w",[r]),
    if  
        R < 33 ->
            io:format ("Vasia peer reviews Erisa's S. Writing");
        true ->
            if  
            R < 66 ->
                io:format ("Lalith peer reviews Erisa's S. Writing");
            true ->
                io:format ("Mariano peer reviews Erisa's S. Writing")
            end 
    end.

What about using eval:

-module(peer).
-export ([draw/0]).

draw() -> os:cmd("ruby -e 'print %w(Vasia Lalith Mariano).choice'").

Hahah! That's avoiding the problem.
