Decode to maps

[chrneumann]

If you know your fields (and their types) only at runtime, there is no way to decode values to them. Structs have to be defined at compile time.

A possible solution would be to support maps as target values. For example:

values := map[string][]string{
    "Name":  {"John"},
    "Age": {"55"},
}
person := make(map[string]interface{})
person["Name"] = new(string)
person["Age"] = new(int)
decoder := schema.NewDecoder()
decoder.Decode(person, values)

There could also be support for nested maps, but I guess it would be ok to just support flat maps with fields like "nested.key".

Other ideas?

Support for nested maps, at least, should definitely be included—since we can already support arrays with arr=...&arr=... etc, we should similarly be able to use maps like m.Key=1&m.Key2=2 (where m is map[string]int).

I agree this would be a good feature. Unfortunately I don't have time to work on this at the moment, marking as HelpWanted.
