Marshalling and Unmarshalling structs to config file

[williambrode]

Is there some good way to marshall/unmarshall a struct to the config file? I'd like to take something like:

type Foo struct {
 a string
 b int
}

map[string]Foo

And be able to write the map to the config file. Trying this with .Set() gives me cannot convert type Foo to Tree but there should be some way to do this using reflection right?
