Currently, optional method parameters and nested object fields therein appear in nondeterministic order in Pydoc pages, presumably due to dict iteration. Regenerating documentation thereby leads to unnecessary changes in the listings of these parameters and fields, which can both confuse users and create misleading diff noise. Iterating over these parameters and fields in a deterministic order would resolve these problems. In particular, using an alphabetic ordering would improve users' ability to locate desired parameters in documentation.
