I think there is only one solution:
If somebody requests INPLACE handling but provides data of
wrong byteorder, I have to throw an exception -- in SWIG terms, the
typecheck returns False (if I remember right).
For me this is just a "last-line of defence" - meaning that I have
most of my functions wrapped by another level of python "convenience"
functions, and those take care of type and byte-order issues
beforehand as needed.
