-For every tuple, that might be returned from our Unifex function (in this case, it is `foo`), there will be generated implementation of result function named `[orginal_function_name]_result_[label]`, where `label` is an atom with type `label` in returned tuple. The type of the first argument of this function will be `UnifexEnv*`, number and types of the rest of the arguments will depend on the number and types of rest of elements in the returned tuple (see the table below).
+The provided `foo` implementation returns the passed argument, by using `foo_result_ok`.

 It is a very simple C code that always returns the same number it gets.
