What's with the use of the var keyword in this situation? Seems quite abusive.

Why? It's just syntactic sugar to avoid having to type the type twice in each line. And it's designed specifically for that, i.e. intended usage rather than abuse.
Please note: 'var' does not mean typeless/nothing/latebound (as in other deranged languages ;-)). Rather it tells the compiler to use the type of the assigned value (type inference).
