12.9.3 Special Comments

(make-special-comment v) → special-comment?

v : any/c

Creates a special-comment value that encapsulates v. The read, read-syntax, etc. procedures treat values constructed with make-special-comment as delimiting whitespace when returned by a reader-extension procedure (see Reader-Extension Procedures).

(special-comment? v) → boolean?

v : any/c

Returns #t if v is the result of make-special-comment, #f otherwise.

(special-comment-value sc) → any

sc : special-comment?

Returns the value encapsulated by the special-comment value sc. This value is never used directly by a reader, but it might be used by the context of a read-char-or-special, etc. call that detects a special comment.
