WTF?!?!

The type in question (vibe.core.net.TCPConnection) is an interface:
http://vibed.org/api/vibe.core.net/TCPConnection
https://github.com/vibe-d/vibe.d/blob/master/core/vibe/core/net.d#L344

The following works just fine:

interface IFoo {}

void main() {
     IFoo i;
     auto b = i is null;
}

Interesting. I was using vibe.d 'v0.8.3-rc.1' (which doesn't appear to 
work on run.dlang.io). But it does seem to work for me if I use 
'v0.8.3-alpha.1'.

I wonder what could have changed to result in this?

It's a struct in "v0.8.3-rc.1" [1]. In "v0.8.3-rc.1" the new 
vibe-core package is the default configuration.
