By the way, you might have retained return (exp); from old C.  C
originally required the parentheses, but they got dropped quite early
on.  The syntax in K&R (1st edition) does not require them, but almost
all the code example in the book still have them!

I took a while to drop them as I came to C from B where they were always
required so I'd got the habit.
