Re: Some problems trying to eliminate 'nil'

While everything that Hlaaftana said is true, there is no reason that
    
    
    proc makeContainer(x: int): Container =
        let f = newFoo(x)
        if f == nil:
            raise new CatchableError
        return Container(foo: f)
    
    
    Run

has to work. It's unstructured control flow and our competitors don't support 
it either.
