i'm well aware that new features don't come free. as a matter of fact, i
could find out exactly how much it would cost.
if i was certain that new notation would improve our product, i would be
having this discussion directly with OTP. as it is, i'm a bit discouraged after
noticing how little use of list comprehensions there actually is.
