With all due respect to Python and not trying to bend it to any other
I believe it trys to do what user expects.
string.split() splits on (clearly documented nonempty) substring.
re.split() splits on RE.
splut(r'\b',...) clearly means (at least for me) 'split on word boundary'
It doesn't reject it (as in r'\b?') nor provide expected behavior.
I understand why it does what it does, but don't agree with it.
