I did send a ~200KB patch do Dan (I supposed it to be to big for the list).

It implements the proposed class hierarchy:

default ... implementing almost nothing, throwing exceptions
|   |
|   scalar ... most of previous default
|      |
|      perlint, perlnum, ...
Sub
Continuation
....

It's not finished, there are many questions ("bitwise or" for perlnum 
....), some other issues (copy a string or not) and so on.

But, it is IMHO a starter, to get towards a consistent class interface - 
and it run's all tests ok.

So if someone else is interested in looking at it, I'll send a copy.

Thanks,
leo
