Well, indeed it's already there in 2.2 :-)

But your method should look like
!Number methodsFor: 'converting'!

because it is not a class method.

You can test whether it is implemented with

   Number canUnderstand: #asNumber

because #respondsTo: checks if the object knows about a message, while 
#canUnderstand: checks whether the *instances* of the objects can answer 
it.  So an alternative would be (not that it makes much sense...)

   Number new respondsTo: #asNumber
