Re: Casting basics (a few questions)

In your example 
    
    
    let value = cast[uint8](address)
    
    
    Run

should be 
    
    
    let value = cast[uint8](address[])
    
    
    Run

You should use UncheckedArray here for nicer syntax: 
    
    
    const size = 3
    
    var buf = cast[ptr UncheckedArray[uint8]](create(uint8, size))
    buf[0] = 0
    buf[1] = 1
    buf[2] = 2
    
    var data = newSeq[uint8](size)
    for i in 0 ..< size:
      data[i] = buf[i]
    
    echo data
    
    
    Run
