Subject: Question on the flip/flop op

With the following code where 'f' is an file handle:

f.each_line{ |line|
	header = 1 .. $.=~$^ ? true : false
	body =  $^ .. f.eof ? true : false }

Say body becomes true after the first \n. What is stopping header from
becoming true again on the next \n? Since it will be between 1 and the $^.
Is the flip flop op somehow storing that $^ was already reached and not to
test the condition again?

Thanks,

Zach
