Please note that if you're using GHC, bang patterns are often much
more convenient than $! or seq when you want to enforce strictness:

Wait, so...
f x = x + 1; f $! (a + b)
and
f !x = x + 1; f (a + b)
mean the same thing?
Well, you learn something new every day... (I guess wanting a function's
arguments to evaluate before the rest of that function is quite a common
thing to want. Neat!)
