My projects work great (~15KLOC). There's one small new problem
involving implicits in package objects, but it's easily worked around.
(It's an ambiguity problem. I'll try to get a bug report together
soon.)

I also finally tried using -optimize in my code, which doesn't seem to
break anything and improves the speed of my unit tests substantially.
(Usually 10-20%, but one long-ish test by as much as 50%!)

-Yspecialize still has issues, but that surely isn't a blocker for a beta.

Lift is building in RC7 and we're preparing to make snapshots of Lift available for Beta 1 when it's released

I've had a go at building the continuations code against RC7. There
were a couple of warnings about inlining, but no real issues. The
inlining warnings are fixed in a post-RC7 nightly.

I hear that the continuations code will be merged into 2.8 after the
beta. Does anyone know if that is correct?
