This is the only part of the explanation I didn't catch. Oh, maybe I
just did. Does this mean you can do:

    r.register([IFile], ISize, "sizer A", FileSize)
    r.register([IFile], ISize, "sizer B", FileSizeExtended)

and then specify the string when doing a lookup? 

If so, I assume in this case you can't use the simple ISize(file) form.

Take care,
