Lately, I've been attempting to improve the performance of a highly
numerically intensive program.
Yet try as I might I cannot seem to define (nor find) an addition function
that is strict in both its arguments.

Using the advice found in the GHC Users Guide I have looked inside the .hi
file and discovered that the functions I define are indeed lazy in their
arguments.

Even when I try something like

data Pair = Pair !Int# !Int#

f (Pair x y) = x +# y

I still discovered to my dismay that the type of the first argument to f is
U(LL).

What can I do to force the arguments to be strict?
