- no value generated errors ... %c will insert a single byte, either from an int in range(256), or from a bytes argument of length 1. what does x = 354 b"%c" % x produce? Seems that construct produces a value dependent error in both python 2 & 3 (although it takes a much bigger value to produce the error in python 3, with str %... with bytes %, the problem with be reached at 256, just like python 2). Is this an intended exception to the overriding principle?

Hmm, thanks for spotting that. Yes, that would be a value error if anything over 255 is used, both currently in Py2, and for bytes in Py3. As Carl suggested, a little more explanation is needed in the PEP.
