[parenscript-devel] Loops that return a value

PS's LOOP works just like CL's in this respect, so what Boris meant to
say was :DOWNTO rather than :TO. There are four options here. :TO and
:DOWNTO are inclusive, while :BELOW and :ABOVE are exclusive:

  (loop :for num :from 1 :to 10 :collect num)
  => (1 2 3 4 5 6 7 8 9 10)

  (loop :for num :from 10 :downto 1 :collect num)
  => (10 9 8 7 6 5 4 3 2 1)

  (loop :for num :from 1 :below 10 :collect num)
  => (1 2 3 4 5 6 7 8 9)

  (loop :for num :from 10 :above 1 :collect num)
  => (10 9 8 7 6 5 4 3 2)
