I tried the spec-example, but it didn’t work for me.
Do you mean using it similar to this test?
(pass-if "R6RS/SRFI-30 block comment syntax overridden"
;; To be compatible with 1.8 and earlier, we should be able to override
;; this syntax.
(with-fluids ((%read-hash-procedures (fluid-ref %read-hash-procedures)))
(read-hash-extend #\| (lambda args 'not))
(fold (lambda (x y result)
(and result (eq? x y)))
#t
(read-string "(this is #| a comment)")
`(this is not a comment))))
Best wishes,
