Actually, it was Remi who came up with this gem when we discussed adding
an isInvalid() method on SwitchPoint.

The thing is, at least where I've used SwitchPoint, having a way of
asking is not as useful as being able to use the pattern to change work
later. So, for example, in Seph I allow "if" to be overridden. If that
doesn't happen I have a fastpath for ifstatements, guarded by a
switchpoint. When someone overrides "if" I want to stop checking for
"if", so I just add the method to check if "if" is overridden to the
switchpoint itself, with a fallback of not doing anything.

I suspect that those kind of patterns are going to be much more common.

I'm not against it. =)
