Thanks for the heads up. I'll think more on this, but you made a
good point here.
And I guess what I was talking about before is that using a
factory method feels klunky to me. If the things I am wrapping
had been written in D they could use default initialization, so
it feels wrong to do otherwise. I also just don't really like
factory methods. They feel like a workaround that the end user
has to deal with. But that's just me.
