I spent a bit of time talking to Guido about the effect of PEP 285 on
the documentation. My own preference is to do the same as the
examples you cite: use the English words "true" and "false", and not
give concrete typed values.
Guido would rather *not* have it this way, but rather document the
exact concrete return values. He'd have me refer to "True" and
"False" in the same way we refer to "None", and refer to the return
type as "bool" (if indeed we're using the new bool type), or, if 1 and
0 are the return values, document them specifically as well.
For function arguments, he'd like to see truth values described as
Boolean, and the values would be the English "true" and "false".
Translations would be able to translate the English words, but not the
True and False values, which are language constants (as constant as
Guido & I may clash over this a few times. ;-(
