I talked to a programmer who knows Scala (among others) and he
mentioned the usefulness of the Option type - a zero or one
element collection (range in D terminology). Here's an article
discussing it:

I really came to love Option when I was working in F#. One of
the things I love about F# is how the language strongly
discourages nulls. Even Anders went on video saying that he
regretted making reference types nullable in C#.
Of course, there's no way to remove the nullable-by-default
nature of reference types in D2, but a guy can dream. =]
