      I guessed Key was bound so I could use for pattern matching.<br>
      It's<br>
      very easy to fix it but I don't know why it doesn't work.<br>
<br>
<br>
    This doesn't works well because the params are not inside of<br>
    binding in closures. The params are the interface with the<br>
    outside world and will be confuse know if a param is a binding<br>
    or not. By default Erlang hasn't binding in function params.<br>
<br>
      Fixed version:<br>
<br>
      delete_key_from_list(Key, StatusList)-><br>
         lists:foldr(<br>
          fun(K, Acc) when K == Key -><br>
          Acc;<br>
       (Another, Acc) -><br>
          [Another|Acc]<br>
          end,<br>
          [],<br>
          StatusList).<br>
<br>
<br>
    This code could be writted as:<br>
<br>
    delete_key_from_list(Key, StatusList)-><br>
       lists:filter(fun(X) -> Key =/= X end, StatusList).<br>
