title: Can TBytes, TByteDynArray, Array of Bytes be safely typecasted to each other?
body: <p>Since <code>TBytes</code>, <code>TByteDynArray</code>, and <code>array of Bytes</code> are all dynamic arrays of bytes, can typed variables be safely typecasted to each other?  (If I have a variable of <code>TBytes</code> can I simply typecast to <code>TByteDynArray</code> when using a method that defines parameters as <code>TByteDynArray</code> and vice-versa?)</p>
