Hi Francisco -

The reason I call this overkill is that the problem we've been talking 
about (Number readFrom: '' readStream) can *literally* be addressed with 
a one-line fix, like here:

   aStream atEnd ifTrue:[^self error: 'At least one digit expected'].

If you need a whole class to do that, I call this overkill ;-)

Cheers,
   - Andreas
