 allowing it to take multiple divisors, chaining several calls to
 divmod() into one.
 
+Pronouncement
+
+ This PEP is rejected. Most uses for chained divmod() involve a
+ constant modulus (in radix conversions for example) and are more
+ properly coded as a loop. The example of splitting seconds
+ into days/hours/minutes/seconds does not generalize to months
+ and years; rather, the whole use case is handled more flexibly and
+ robustly by date and time modules. The other use cases mentioned
+ in the PEP are somewhat rare in real code. The proposal is also
+ problematic in terms of clarity and obviousness. In the examples,
+ it is not immediately clear that the argument order is correct or
+ that the target tuple is of the right length. Users from other
+ languages are more likely to understand the standard two argument
+ form without having to re-read the documentation. See python-dev
+ discussion on 17 June 2005.
