2.8 collections and preview

Hi Martin,

It's been on my to do list for a while now to give the new collections
library a bit of a kick around, see how they work and shake out any
problems. I've not yet been able to find time to do so unfortunately
(I've been massively busy). Hopefully I'll find time to do so soon
(this sunday might be possible) and, when I do, I'll definitely try to
put some work in to fixing the unfinished bits.

Could you clarify what you mean by a preview? I'm assuming we're
talking about something which is very decidedly alpha quality rather
than a release candidate per se?

David

Hi David,

your contributions will be most welcome. Thanks! Yes, the preview is
not an RC, and not even a beta.

Cheers
