While that is true I would not advocate doing that for two reasons.

1) There is no guarantee that there is > 0 views and controls
2) In the future there will be other types of control (eg corba)

the WORKBOOK_FOREACH_{VIEW,CONTROL} macros are the safe way to walk
those data structures.  In the future we'll need to consider how to
associate a wbc with the execution of a python routine.
