wingo pushed a commit to branch wip-goops-refactor
in repository guile.
commit 77f85184f9b6f5eae916149d4f3b4001f441de67
Author: Andy Wingo <address@hidden>
Date: Sat Jan 10 23:20:47 2015 +0100
Remove scm_c_extend_primitive_generic
* libguile/goops.h (scm_c_extend_primitive_generic): Remove public
interface. This was introduced in 2003 with the "extended" generics
but never documented, unused as far as I can tell, and is better
accessed from Scheme.
* libguile/goops.c: Remove support for scm_c_extend_primitive_generic.
Simplify capture of change-class.
