Using a Case Statement inside a template

[phillvancejr]

I'm messing around with templates and can't get passed this template/generic 
instantiation of 'test' from here. What is wrong with this code? 
    
    
    let val = 10
    template test(val: typed) =
        case val:
        of low(int)..<5:
            echo "under 5"
        else:
            echo "5 or above"
    
    test(val)
    
    
    Run

I'm trying to get to something like this: 
    
    
    template test(stuff: untyped): untyped =
        stuff
    
    let val = 10
    
    test:
        case val:
        of low(int)..<5:
            echo "under 5"
        else:
            echo "5 or above"
    
    
    Run

I'm not sure what this error means and why this code won't work. Any help is 
appreciated
