Title: Function name conflicts with an imported function.
Goal: deny
Parameters: [{file,"ef3.erl"},{posrange,{131,235}},{name,"sort"}].
Documentation: Similar to ef2, but this time FunName (the name of the function to be produced by the refactoring) conflicts with an imported function, sorting:sort/2. Another function name should be requested from the user, or a compensation (remove import) should be proposed.
