Parametrically sized localparam assignment

So, to answer my own question, this appears to work, while not entirely elegant:

 
 `define MAX_BAR 128
  typedef logic  bar_t;
  function bar_t  makeFoo (input integer x);
    bar_t  bar;
    integer i;
    for (i = 0; i < x; i++) begin
      bar = i + 1;
    end
    return bar;
  endfunction
  . . .
  localparam bar_t  FOO = makeFoo(SIZE);

I'd like to be able to size everything only as large as I need it. But for static analysis, it's probably sufficient for most uses to set an upper bound like this.

Again, if anyone has a cleaner way to do this, I'd be interested to see it.
