Title: The selected part contains a call of the function to be generalized
Goal: Generalize the function `f/1' by selecting the expression `f(Tail)', the new parameter is `K'.
Parameters: [{file,"gen16.erl"},{posrange,{85,91}},{varname,"K"}].
Documentation: The selected expression contains a call of the function to be generalized. Result in this transformation the application calls the original function with arity one (`f([1,2], fun(Tail) -> f(Tail) end)'), but after the transformation it will not exist. In this case the refactoring denied the transformation.
