Subject: [ruby-core:26325] [Feature #1697] Object#<=>

Issue #1697 has been updated by Marc-Andre Lafortune.


Given your comment, and Eero rightly pointing out that it's better to use eql? than == for this case, 

diff --git a/object.c b/object.c
index 9f7537f..8f20621 100644
--- a/object.c
+++ b/object.c
@@ -1123,7 +1123,7 @@ rb_obj_not_match(VALUE obj1, VALUE obj2)
 static VALUE
 rb_obj_cmp(VALUE obj1, VALUE obj2)
 {
-    if (obj1 == obj2 || rb_obj_equal(obj1, obj2))
+    if (obj1 == obj2 || rb_eql(obj1, obj2))
       return INT2FIX(0);
    return Qnil;
 }


Note: I'm not saying that obj1 == obj2 is redundant. I'm saying rb_obj_equal is.
