Thank you very much for your report.

The sample implementation is based on SRFI 148 (in particular, to
demonstrate the capabilities of the macro system proposed in SRFI 148).
However, the sample implementation of SRFI 148 has undergone a few
changes, making it compatible with recent versions of Chibi and Larceny
(see the mailing list of SRFI 148 where the issue - namely how literals
are matched in syntax-rules macros - is discussed at length).

The implementation of SRFI 148 included in the sample implementation of
SRFI 150 was never updated. I am going to send a pull request with
updates to Arthur, so that it will be fixed (and you might try the
corrected version).

Best,

Marc
