It's funny, but I was recently doing some game prototyping and needed a
very fast, garbage-free way of allocating lots of small, short-lived
objects.

I thought "Ha! I have a block allocator mixin for just this purpose!"
...until I remembered I was programming in C# and not D.

So now I have to create an array of pre-allocated objects, and have a
protocol for assigning and returning them.  Plus, I have to have a
unique pool for each subclass since I can't use casts to override the
type system.

Urgh.
