Re: assign an object variant kind for unsafe memory block

[treeform]

Auxiliary copy object does not fill too bad though:
    
    
    type
      Kinds = enum
        kA, kB, kC
      ExampleBlock = object
        case kind: Kinds
        of kA: a: int
        of kB: b: string
        of kC: c: uint16
        otherFields: array[16, int]
    
    when isMainModule:
      echo "Sizeof block, ", sizeof(ExampleBlock) # Is a union after all
      let kindcrash = cast[ptr ExampleBlock](
        alloc0(sizeof(ExampleBlock))
      )
      var copyObj = ExampleBlock(kind:kb)
      copyObj.b = "String Test"
      kindcrash[] = copyObj
      
      echo kindcrash.kind
      echo kindcrash.b
    
    
    Run
