#templet $counter {
  #set $digit = $digit + 1
  #if ($digit < 10) {
    [$digit < 10]
    #eval $Self using { "digit": $digit }
  } #else {
    [$digi >= 10]
  }
}
#eval $counter using { "digit": $digit }

gives me:-

[1 < 10] [2 < 10] [3 < 10] [4 < 10] [5 < 10] [6 < 10] [7 < 10] [8 < 10] [9 < 
10] [10 >= 10]
