Literals of type <cf>int set</cf> look like <cf> [ 1, 2, 5..7 ]</cf>. As you can see, both simple values and ranges are permitted in sets. For pair sets, expressions like <cf/(123,*)/ can be used to denote ranges (in - that case <cf/(123,0)..(123,65535)/). + that case <cf/(123,0)..(123,65535)/). You can also use <cf/(123,5..100/ for range + <cf/(123,5)..(123,100)/.
