Thank you very much for publishing this first draft, Arthur.

I saw that you added a "see also"-reference to SRFI 148. While SRFI 148 could have made good use of SRFI 188, another reference would be SRFI 93 (the SRFI on syntax-case macros, which was withdrawn in the process of finalizing R6RS) because it describes the R6RS version of let(rec)-syntax.

Here's the abstract:

Splicing binding constructs for syntactic keywords are versions of let-syntax and letrec-syntax that can be used in a definition context in the same way as begin.
