you think I am arguing?
i am not (excpet possibly on symantics)
your "you must see the whole function on one page" stipulation should be
treated as guidance & not a rule
preferably it should read "You 'SHOULD' be able to see the whole function
on one page.
and as you quite rightly state there are always exceptions as enshrined
in the zen
