Post a bug report about this: the documentation should be clearer. If 
it would
say "if you try to byteswap() on unsupported values you'll get an 
exception"
you know that you don't have to worry.

And practically: I wouldn't worry about it. As the typecode is stored 
with the
array I can't imagine an implementation that would break things on 
byteswap()
without telling you anything.
