Yes, I understand the paradigm, nil is nothing is zero, empty is
nothing is zero...
But frankly, do you think '' forms a valid Number ? In every context ?
So yes, this is expected, and can break compatibility, but sometimes
this is necessary.

If you want to keep this behaviour, you have to use an explicit rule like:
asNumberOrZero
� ^Number readFrom: self ifFail: [^0]

Hope this helps...
