Hm... Now I'm confused.
"clist is similar to a set"
I understand that as I can define eclist variable in a similar way:
eclist var;
var = [ ... ];

I tried that:
filter Reject_Static
eclist cmn;
{
        cmn = [ (ro,MyASN,10856), (ro,MyASN,3) ];
	print cmn.len;
	zzz;
        bgp_ext_community.add(cmn);
        accept;
}

protocol static TEST {
        import filter Reject_Static;
        route 185.61.244.0/22 blackhole;
}

"print cmn.len" does not print anything neither in syslog nor in stderr,
when running with -d switch.
