6611 :: "||" operator ? : Is there a corresponding operator for iterables ?

  Is there a corresponding operator for iterables ?

  From the snippet hereunder, I'm assuming that this operator is for dealing with vectors (since it appears in a range expression):

  
  import strutils
  
  var x=0
  for i in 1||1000:
      inc x
      echo "[$1]=$2" % [$i,$x]
  Run

  This is an operator to parallelize a loop with OpenMP.

  Do not use inc on a global variable with it as there would be no synchronization and what you will get in x will be random.

  Where do you see this || operator? I have never seen such an operator in Nim...

  Thank you. Wise observation. What was I thinking?

  I happened to just be adding some very preliminary "guts" for a module similar to Python's multiprocessing to wrap an MT-UNSAFE C facility when I noticed this question. No || operator yet, but maybe someday. (It is a slightly different topic, of course, since parent-child sharing is more restricted, but perhaps of interest.)
