No. Ethan is still the only one who can push the release button. Otherwise
I'd have cut a release quite a while ago.

Oh. Can't C++ handle types as variable names? That's pretty weak tbh.
I'll make a note of it. In the future, the object types will be either
"struct <type>" or "<type>_object". We save no typing for either case,
and abbreviating "_object" to "_obj" seems a bit silly to me. We'll
probably go with "struct host". That will also make it possible to
name instances of the structs to the type they're referring to, such
that

 struct host *host;

works well. Does this also work nicely with C++, or do we have to play
prefix/suffix games?

I dislike such abbreviations too, and I mean to get rid of them when
refactoring code that uses them, but that can't happen until we get
rid of the types named as objects without suffixes.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
