Yes, for example in a function called rt_import_all, I use:

  if net_martian() then
  {
    print "rt_import_all: ", net, " from ", from, ": net_martian() returned true!";
    return false;
  }

so I imagine you could do:

  if ( is_martian() ) then {
    reject "prefix rejected by is_martian: ", net, " from ", from, " bgp_path.first ", bgp_path.first;
  }
