Go(lang): Use a Function to Modify a struct via Reflection

I just started learning Go recently and I must say, it's been a lot of fun. The first real difficulty I've had with the language has been trying to use reflection to set a field on a struct, inside of a function. I found some decent examples, but none that were quite fitting, so I thought I'd share my solution here.

So, just for the fun of it, let's say we have a struct that we know will "always" have a field Brewery:

type Beer struct {
    Brewery string
}

Note that Brewery is public (sorry for the term, my non-Go experience is showing).

Now let's say we want to create a function that always sets the Brewery to "Dogfish Head", but we want it to operate on the general interface and use reflection (for whatever reason):

import "reflect"

func breweryToDFH(thing interface{}) {
    reflect.ValueOf(thing).
        Elem().
        FieldByName("Brewery").
        SetString("Dogfish Head")
}

Finally, to call it, a pointer must be used, e.g.

beer := Beer{}
breweryToDFH(&beer)

And that's all! As one coming from the dynamicity of Ruby, this seems kind of roundabout. So if you know a way to simplify, please feel free to comment. Also, there is a good deal of error handling that should be done here, so for that, I will defer to a stackoverflow post.

Happy "Go-ing"!
