Varnish VCL "Symbol not found: std.querysort"

Question

I am copying some VCL rules from this handy template and running on the latest stable Varnish4. However this section of the VCL:

vcl 4.0;

sub vcl_init {
    # ...

    # Normalize query arguments
    set req.url = std.querysort(req.url);
}
                  ^

Returns this error:

Should I include a mod or define std somehow?

Yes! I stumbled on the answer inside another answer. Adding import std; at the top of the script stopped the error.

vcl 4.0;
import std;

sub vcl_init {
    # ...

    # Normalize query arguments
    set req.url = std.querysort(req.url);
}

Thanks! Personally I would put modify the URL in vcl_recv instead of vcl_init. Typically vcl_init is only used to initialize mods. – Martijn Heemels Mar 22 '16 at 16:57
