Title:
  Conflict with a locally defined function
Goal:
  Contract the first two argument of `elem/3' function into tuple.
Parameters:
  [{file,"export.erl"}, {posrange,{43,45}}].
Documentation:
  Accept. The selection is "A,B". If we contract the first two
  agruments of the `elem/3' function into tuple that will create a new
  function `elem' with arity 2, that could introduce a conflict with a
  locally defined function `elem/2' in `import' module. The import
  form is removed from the module and the function application is
  qualified, thus the conflict is resolved. In the `import2' module,
  there is no conclict with co function, the import form is just
  updated with the new arity.
