gh-143886: Ensure function annotations are returned in order of definition ( #143888 )
...
Ensure function annotations are returned in order of definition
Previously, when getting type annotations of a function, normal
arguments were returned before positional-only ones in the dictionary.
Since `functools.singledispatch` relies on this ordering being correct
to dispatch based on the type of the first argument, this issue was
causing incorrect registrations for functions with positional-only
arguments.
This commit updates how annotations are generated so that
positional-only arguments are generated and added to the dictionary
before normal arguments.

creation, as documented, but keeps it in the same code object allowing
optimization.
