I understand that it appears logical, but <=3D> is a *comparison* operator,= used to compare with *other* values during sort/min/max. It's pretty much = useless if the only valid comparison is with itself. What's the use case fo= r `[true,true].min =3D=3D true` but `[true,anything_else].min #=3D> Argumen= tError` ? I can't think of anything reasonable. At least if `true<=3D>true`= was nil, that would tell us this value is not comparable with any other va= lue. But I'm not suggesting we change this now, it seems too backward incom= patible. ---------------------------------------- Feature #13933: Add Range#empty? https://bugs.ruby-lang.org/issues/13933#change-104732 * Author: ted (Ted Johansson) * Status: Open * Priority: Normal ---------------------------------------- Range already responds to #size.
