How do I define a symbol-macro in Scheme?


(require mzlib/defmacro)
(define-macro 16-bit-mask #xFFFF)
doesn't work.

R6RS explicitly forbid usage of digits for the first character of as identifier.
See :

4.2.4 Identifiers
[...]In general, a sequence of letters, digits, and “extended alphabetic characters” is an identifier when it begins with a character that cannot begin a representation of a number object.[...]

Also, <identifier> in "4.2.1  Formal account".
