I would clearly rate this a bug, because there are negative Integers 
in class Integer, and the semantics of #asXyz is that Xyz is a class. 
Even in the rest of the computing world Integers mostly if not always 
include negatives. 

Integer readFrom: ( ReadStream on: '-1' ) answers -1, and that is 
the expected implementation. 

Furthermore the compiler converts '-1' to Integer -1, and so should do 
this method. Everything else is totally unexpected.
