Hi all, this is JFYI to be aware of an Ops.is() limitation. During debugging a crash in yast2-sound [1] I found out that Ops.is() implementaion does not properly support all data types. The problem is with typed maps/lists, the internal data type is not checked at all. Example: Ops.is({}, "list") => false Ops.is([], "list") => true Ops.is([1, 2], "list<integer>") => true But also: Ops.is([1, 2], "list<string>") => true This makes a trouble when the internal data type is important: if Ops.is(foo, "list<string>") ... elsif Ops.is(foo, "list<integer>") ... I have checked all occurencies in Yast ([2]) and only yast2-sound seems to be affected therefore I have fixed it just there. See the pull request [3], I simple replaced Ops.is() by native Ruby #is_a? method [4].
