Re: I'm fed with Nim , I guess.

[Arrrrrrrrr]

I have never given a proper look at threading on nim. Is it safe to assume this 
code won't produce any race conditions or undefined behavior? 
    
    
    import random, threadpool
    
    type
      RandGen = ref object
        rands: seq[Rand]
      Rand = object
        list: seq[int]
    
    var gen: RandGen
    
    proc randomize(i: int) =
      for _ in 0 ..< 10: add(gen.rands[i].list, rand(10))
    
    proc main =
      randomize()
      gen = RandGen(rands: @[Rand(), Rand(), Rand()])
      
      for i in 0 ..< len(gen.rands):
        proc safeRandomize(i: int) =
          {.gcsafe.}: randomize(i)
        
        spawn safeRandomize(i)
      
      sync()
      
      for rand in gen.rands:
        echo rand.list
    
    main()
    
    
    Run
