Subject: "define-constant is only allowed in a <body>"

I have a module named (mapping), which contains a thing that I have called
"mapping", which is a nice functional interface to mutable hash tables
(based on SRFI-17):

Therein, you can also find the following definition of define-mapping:

(define-syntax-rule (define-mapping (mapping-name key) default-value)
   (define-early-constant mapping-name
      (mapping (key) default-value)))

where define-syntax-rule is defined in a straightforward way in another

When I try to use this code from yet another module -- more specifically,
this one:


(define-mapping (on-key-press code) never)

I get the error message

define-constant is only allowed in a <body>

but when I use the expanded version

(define on-key-press (mapping (code) never))

everything works.

I wonder what could be the reason of Kawa's behavior.
