The topic is discussed here:

As discussed in the thread, when verifying that an argument names an
existing object, it is usually also appropriate to verify that the named
object is of a particular type (or can be converted to a particular
type), which could already be done with syntax like
"$userstring^{commit}". But if, for example, you want to avoid
unwrapping tags but also want to verify that the named object really
exists, "$userstring^{object}" now provides a way.

And what do you have against test suites? :-)
