Reworking "c things" like static const unsigned char clcidx[19] =

[catswhiskers]

Why does this work?:
    
    
    var
          tab: array[ 19, uint16]
    for i, v in [ 16.uint16, 17, 18, 0,  8, 7,  9, 6, 10, 5, 11,  4, 12, 3, 13, 
2, 14, 1, 15]:
       tab[ i] = v
    
    
    Run

but not for
    
    
    var
         tab: array[ 16, uint32]
    for i, v in [ 0x00000000.uint32, 0x1DB71064, 0x3B6E20C8, 0x26D930AC, 
0x76DC4190, 0x6B6B51F4, 0x4DB26158, 0x5005713C, 0xEDB88320, 0xF00F9344, 
0xD6D6A3E8, 0xCB61B38C, 0x9B64C2B0, 0x86D3D2D4, 0xA00AE278, 0xBDBDF21C]
       tab[ i] = v
    
    
    Run

which always fails with

Error: type mismatch: got ‘int64' for ‘0x00000000EDB88320‘i64' but expected 
‘uint32‘

So that I have to go round the houses with this
    
    
    var
        tab: array[ 16, uint32]
        i: int
    for v in """0x00000000, 0x1DB71064, 0x3B6E20C8, 0x26D930AC,
                        0x76DC4190, 0x6B6B51F4, 0x4DB26158, 0x5005713C, 
0xEDB88320,
                        0xF00F9344, 0xD6D6A3E8, 0xCB61B38C, 0x9B64C2B0, 
0x86D3D2D4,
                        0xA00AE278, 0xBDBDF21C""".split ", ":
       let s    = v.strip
       tab[ i] = s.parseHexInt.uint32
       inc i
    
    
    Run

which is ok ish but irritating?
