Thanks! I've pushed repairs for these problems, mreged recent changes
from the main development branches, and updated the snapshot here:

I’ve just found something that I expected to work, but didn’t:
#lang racket/base
(require racket/splicing (for-syntax racket/base))
(splicing-local
[(define x 1)]
(define-syntax outer-x (make-rename-transformer #'x)))
outer-x
;. outer-x: unbound identifier in module in: outer-x
This works
Yes, I overlooked `splicing-local`, and I'll repair it. Thanks for the
report!

. Awesome that Racket keeps pushing the envelope on
meta-programming. It /is/ exciting. I'm somewhat quiet because I'm still
absorbing it as I get the time. There has been chatter on IRC too. Also,
very cool that mflatt is being so open with the community during the dev
cycle. Bring it on.
