There is another improvement you can do: you are currently using
cfg := Config{Name: &nameField}
r := reflect.ValueOf(cfg)
which means that 'r' will contain a copy of 'cfg' and will not be settable.
If instead you use:
r := reflect.ValueOf(&cfg).Elem()
then r will contain a *pointer* to the original 'cfg' and can modify it
(the reflect.Value 'r' is settable).
In turn, this also allows to declare 'Config' as follows:
```
type Config struct {
Name String
}
```
i.e. removes the need to use a *pointer* to String.
You also need some minor adjustments to the rest of the code...
A complete example is:
