Yes, sorry, GHC's strictness analyzer.
What I meant with this email is that I guess that for a strictness analyzer,
the information that a function is strict in an argument *independent from
the other arguments* would not be good enough in
Consider the function
cond x y z = if x then y else z
I guess we can certainly say cond is strict in x.
But what about y and z?
If x is true, then cond is strict in y
If x is false, then cond is strict in z
So we can't really say cond is lazy nor strict in its second or third argument.
