Hi,
The following program works fine under GNU Guile 2.0.12:
(use-modules (oop goops))
(define-generic native-type)
(define-method (native-type (i <integer>) . args) 0)
(define-method (native-type (i <real>) . args) 1)
(define-method (native-type (b <boolean>) . args) 2)
(native-type 1)
(native-type 1.3)
(native-type #f)
(native-type 1 1.2)
(native-type 1.4 2)
(native-type 1.4 2 3)
(native-type 1.4 1.5)
(native-type #f #t)
However under GNU Guile 2.1.4 [1] it fails with an error in
"multiple-arity-dispatcher":
oop/goops.scm:1336:2: oop/goops.scm:1336:2: In procedure vector-ref: Value out of range: 3
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.
Getting the backtrace didn't work:
,bt
In oop/goops.scm:
While executing meta-command:
ERROR: In procedure vector-set!: Value out of range: 5
Regards
Jan
