Re: How to chain prodecure calls that mutate a reference object ?

[Hlaaftana]

I know this code isn't meant to be used, but the given answers for `var Child` 
were wrong to the point where I have to respond. We want the variable 
`self.child` not `child`. No need for templates or anything
    
    
    type
      Child* = object
        value: int
      
      Parent* = object
        child: Child
    
    
    proc set_value*(self: var Child, value: int): var Child {.discardable.} =
      self.value = value
      self
    
    proc get_child*(self: var Parent): var Child =
      self.child = Child()
      self.child
    
    
    var parent = Parent()
    
    parent.get_child().set_value(10)
    
    echo parent.child.value # 10
    
    
    Run

Again, this isn't idiomatic code, just had to point it out.
