     class iv{
       private byte[] buffer;
       private ulong writePos;
       private ulong readPos;

       this(){}

       void write(T)(T value) if (is(T == uint)){
         buffer ~= nativeToLittleEndian!uint(value);
         writePos += uint.sizeof;
       }

       uint readUint()
       {
         assert(readPos == 0);
         uint value = 
littleEndianToNative!uint(cast(ubyte[uint.sizeof])buffer[readPos..readPos+uint.sizeof]);
         readPos += uint.sizeof;
         return value;
       }

       uint readUint_test()
       {
         assert(readPos == 0);
         uint value = 
littleEndianToNative!uint(cast(ubyte[uint.sizeof])buffer[0..0+uint.sizeof]);
         readPos += uint.sizeof;
         return value;
       }
     }


void main()
{

       auto cc = new iv();

       uint ptr = 1000000;

       cc.write(ptr);
       writeln(cc.readUint()); //not works
       writeln(cc.readUint_test()); // works

}

The readUint_test its working while the readUint not.
