Extended Description

Attached is a condesed example from Sonias work in which WLFusion behaves wrong.
for( i=0; i<25; i++) {
    z = z + p;
    r = r - a;
    beta = sum(r);
    p = r + (beta * p);
}
In this code fragment, WLFS fuses the computation of r into the computation of p, rendering the r in sum
(r) a dead reference.
