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):
https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/src/mapping.scm
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
module.
When I try to use this code from yet another module -- more specifically,
this one:
https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/src/panel.scm#L130
as
(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.
