Someone else probably has a better answer, but I noticed this too.  It seems
the operand *must* be declared as an operand before being used in the
function, i.e.,

 #local Faktor=<1,1,1>*0.75;
#local Fx=Faktor.x;
#local Fy=Faktor.y;
#local Fz=Faktor.z;
P2(x*(Fx+0),y*(Fy+0),z*(Fz+0))

I don't know the reason though
