Removed the T prefix for the style traits
More work as described in #10185.
I am getting _extremely_ weird compile-time errors with this one, when it's trying to expand the `lazy_static!` macro. I think I'll need help getting that part sorted out. The rest should be pretty OK.
Anyone has ideas on how to resolve it?
