LGTM, and a nice addition to Scheme.

The only thing is what to call the operators. The word "splicing"
reminds me of the ,@ unquote-splicing syntax which is a different thing,
but Racket is already calling it `splicing-let-syntax` and compatibility
is good.

Can you add a note to the rationale about the fact that the splicing
versions are not a drop-in replacement for the standard non-splicing
ones and hence they need to have different names?
