I think the golang package only deals with byte-oriented interfaces. Most CPUs 
can't address units smaller than a byte anyway, so endianness isn't really 
observable from software. So the bit-endianness of individual bytes is 
determined by whatever you are passing those bytes to (presumably some hardware 
port?).

Ah, I've been thinking about this issue too much and have confused myself.

And, I have expressed it as an XY Problem!  :-(

My real question should have been: if I write a byte to a file on one 
architecture, will the byte be the same on all other architectures (i.e. 
386, amd64, arm, s390x, ppc64le) if read by a Go program on them?

Sorry for my confusion.  :-)

Thanks,
Glen

Ack! Sorry.

I was referring to *bit endianness*
