You have to get the values from the array 'manually', the prism won't do 
it for you, see example below:

---%<------%<---

#declare A=array[5]{<1,0>,<0,1>,<-1,0>,<0,-1>,<1,0>}

#declare NrPoints=dimension_size(A,1);

prism{
  linear_spline
  linear_sweep
  0,
  1,
  NrPoints,
  #declare I=0;
  #while (I<NrPoints)
    #local P=A[I];
    P
    #declare I=I+1;
  #end
  pigment { rgb 1}
}
