It's named and used in the model of GNU's seq.

3 → 1, 2, 3
1 2 4 → 1, 3
-3 → -1, -2, -3
1 4 → 1, 2, 3, 4
1 -2 → 1, 0, -1, -2

Example: seq with range and after

You can use seq in combination with range and after. The following will return 19 elements:

{{ range after 1 (seq 20)}}
{{ end }}

However, when ranging with an index, the following may be less confusing in that $indexStartingAt1 and $num will return 1,2,3 ... 20:

{{ range $index, $num := (seq 20) }}
$indexStartingAt1 := (add $index 1)
{{ end }}
