Is there any simple way to redefine an expression without (all)warnings? The following code gives a warning for replacing the expression F, though I have explicitly declared F will be dropped unless any redefinition is given:
On allwarnings;
L F = 2;
.sort
Drop F;
L F = 3 * F;
P;
.end

Drop F;

In principle, one can copy the expression to a temporary expression like
On allwarnings;
L F = 2;
.sort
Drop F;
L tmp = F;
.sort
Drop tmp;
L F = 3 * tmp;
P;
.end
