I don't want to press this point; it's mostly about the expectations one
has developed about C, and there are reasonable arguments on both sides.
If we can compromise on structure typedefs, I'll be happy.

It seems dangerous to promise that a library can create a private event
loop that will use the same implementation as the application's event
loop, even when the application is not aware of libverto. This seems
difficult to deliver because:
1. Testing whether you're linked to a particular library seems
questionably portable.
2. The application may be using an event loop which libverto isn't aware
of.
3. The application may be using a private event loop implementation
which libverto can't possibly be aware of.
If the application is aware of libverto, it can use verto_set_default()
(although I'm not sure whether the current interface allows an
application to set the default to a private event loop implementation;
I'd have to check that).
