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
