The fact that Object is not const-correct is a huge problem. http://d.puremagic.com/issues/show_bug.cgi?id=1824 covers that, but I don't know when it's going to be fixed. http://d.puremagic.com/issues/show_bug.cgi?id=3748 which deals with inout probably has to be fixed first. So, I don't know whether there's really an issue with Variant itself, but the fact that functions like toHash() opEquals() aren't const is a big problem which is supposed to be addressed at some point but hasn't yet. - Jonathan M Davis
