I agree ("in the face of ambiguity..."), although I understand that it 
wasn't
obvious that I do from the way I asked the question, which I was expecting
Greg to answer :)

I beg to disagree.  I don't know whether you are Dutch or not, but most of
the Python users aren't; one of the reason PEPs exist is to explain what
*should* "be obvious at first" when one is Dutch ;-)  Apart from joking,
PEPs should be a record of beating/thinking the PEP subject to its death:
"The PEP author is responsible for building consensus within the
community and documenting dissenting opinions."
