Nice work!
Anytime I see things like this it makes me wish D would adopt
some form of pattern matching.
I've been using F# a lot lately, and I'm in love with how
expressive it can be in certain cases, i.e.:
```fsharp
let (|Seconds|NotANumber|) (str : string) =
let mutable value = 0.0
match Double.TryParse(str, &value) with
| true -> Seconds value
| false -> NotANumber
...somewhere in an expression/function
match model.Duration with
| Seconds s -> ValidRequest {
...omitted
}
| NotANumber -> InvalidRequest "Duration is not a valid
number"
```
