review queue: next?

[Dicebot]

While Jacob is working on improving std.serialization, there is 
some time to do more reviews. Review manager role does not seem 
to be very stressing, so I can step up as one for any of the 
projects currently in queue as soon as their authors express the 
desire to do so.

Personally, I'd love to move forward with std.d.lexer - Brian, 
what is your opinion on this?
