Would be useful, but would also be quite some work to make that happen (need to create a little endian function for each primitive to/from bytes, then I’ll need to add a check to each function of the reader/writer classes to either use the big endian or the little endian function).
By the way, why do you need a little endian reader though? The network byte order is big endian (assuming you get the data from a remote source/place)?
