Title: Function name conflicts with another function defined in the same module.
Goal: deny
Parameters: [{file,"ef2.erl"},{posrange,{104,208}},{name,"sort"}].
Documentation: Similar to ef1, but this time FunName (the name of the function to be produced by the refactoring) conflicts with another function, sort/2, defined in the same module. Another function name should be requested from the user, or a compensation (rename function) should be proposed.
