Yes, thanks, that does make sense.  However, while:

  p foo (4 + 6) / 2

produces a warning, so does:

  p foo (4 + 6)

The difference here is that while the first one could possibly be
interpreted as (foo(10)/2) or (foo(5)), the second could only be
interpreted as (foo(10)).

Perhaps, though, the warning is still good, because I might always want to
add a /2 later.
