Any news on library refactoring?

I'm not on IRC, so I don't know what's new these days.  Any news on the core
library refactoring?  I have to be honest, I'm interested because I'm working
on my own language (which happens to have a very similar VM - can't beat Io),
and am researching core libraries.

There are a few funny things you can do in Io right now.  Yes, I mentioned this
before :)

"abc" sum
"abc" product

I know a sequence is a general container, but to me it feels funny to have
methods available which don't make sense in that context.  Would simply moving
them to Vector work?  I think of a Vector as an n-sized array of numbers, not
just 2d or 3d vectors - is this correct?

Just some thoughts...
