Code example v0.4 page 71 does not compile

[AustinBGibbons]

Was trying to use the argmin syntax from the guide, example does not compile

Proc foo(G: Graph, S1: Node_Set(G), A: N_P<Int>(G)) 
{
  Node_Set(G) S2;
  Foreach(s: S1.Items) (s.A >0) {
    S2.Add(s);
  }
  While(True) {
    Int m; Node(G) am;
    m = +INF;
    Foreach(s: S2.Items) {
    m <,am> min= s.A <,s>;
    }
    S2.Remove(am);
  }
}

Expected: compiles Actual:

make[1]: Entering directory `/lfs/madmax/0/austin/Green-Marl/apps/src'
../../bin/gm_comp -o=../output_cpp/generated -t=cpp_omp  dijkstra.gm
dijkstra.gm:36:7: error: syntax error, unexpected '<' (near ',')

The syntax has been changed. Try <m; am> min = <s.A; s>

Instead.
