'beresp.ttl': cannot be set in method 'vcl_hit' in Varnish 4.0

Question

I am trying to import my old Varnish configuration to version 4.0.

sub vcl_hit {
     if (req.method == "PURGE") {
          set beresp.ttl = 0s;
          return (synth(200, "Purged."));
     }
}

Error I am getting:

Message from VCC-compiler:
'beresp.ttl': cannot be set in method 'vcl_hit'.
At: ('input' Line 135 Pos 15)
          set beresp.ttl = 0s;
--------------##########------

Running VCC-compiler failed, exited with 2

So how do I update that?
