Here's a simple test:
-----------------------------------mm.scm-----------------------------------
(define-module (mm)
#:use-module ((rnrs) #:select (define-record-type)))
(define-record-type aaa)
(define-record-type bbb)
--------------------------------------end----------------------------------------
When I import (mm) module, there's a warning:
---------------------------------------------------------------------------------------------------
mm.scm:6:0: warning: shadows previous definition of `dummy-1a78708d3c9406a3' at mm.scm:4:0
---------------------------------------------------------------------------------------------------
It seems aaa was overwritten by bbb.
Comments?
Best regards.
