bpo-37979: Add alternative to fromisoformat in documentation (GH-15596)

2019-08-29T14:54:37+00:00

Adds a link to `dateutil.parser.isoparse` in the documentation.

It would be nice to set up intersphinx for things like this, but I think we can leave that for a separate PR.

bpo-37947: Avoid double-decrement in symtable recursion counting (GH-15593)

2019-08-29T13:46:20+00:00

With `symtable_visit_expr` now correctly adjusting the recursion depth for named
expressions, `symtable_handle_namedexpr` should be leaving it alone.

Also adds a new check to `PySymtable_BuildObject` that raises `SystemError`
if a successful first symbol analysis pass fails to keep the stack depth
accounting clean.
