In "define-struct" and "struct", should I be able to provide both
"#:constructor-name" and "#:extra-constructor-name"?
Both of the following programs give me an error on the last form, under
Racket 5.2.1.
Program #1:
#lang racket/base
(define-struct myc (field1) #:constructor-name make-myc-c)
(define-struct mye (field1) #:extra-constructor-name make-mye-e)
(define-struct myce (field1)
#:constructor-name make-myce-c
#:extra-constructor-name make-myce-e)
;; ERROR: define-struct: multiple #:constructor-name or
#:extra-constructor-name keys specification#<syntax:8:2
#:extra-constructor-name> in: "#:constructor-name or
#:extra-constructor-name keys"
Program #2:
#lang racket/base
(struct myc (field1) #:constructor-name make-myc-c)
(struct mye (field1) #:extra-constructor-name make-mye-e)
(struct myce (field1)
#:constructor-name make-myce-c
#:extra-constructor-name make-myce-e)
;; ERROR: struct: multiple #:constructor-name or
#:extra-constructor-name keys specification#<syntax:8:2
