* Add support for generic optional parameters
* Tests for passing non-optional arguments to optional parameters
* Remove now-redundant is_class_value handling
This parameter has since been removed from infer_type_vars methods,
much simplifying the code.
* Remove "typing." prefix from compiled signature param
* Don't print default "None" for Optional params
* Don't remove 'typing.' prefix if symbol doesn't come from typing module
* Revert "Don't print default "None" for Optional params"
This reverts commit 8db334d9bb.
* Make sure "typing." doesn't appear in the middle
* Make sure only "typing." prefix is removed and not it's entries in the middle
* Use inspect.formatannotation() to create an annotation string
* Update AUTHORS.txt
* Add test for compiled param annotation string
* Replace Optional in test with other typing facilities
in order for test to be forward-compatible with 3.9
* Add an empty string fallback for Python 2
* Move _annotation_to_str back to original position
* the cache directory should really be %LOCALAPPDATA%
* ~ is not a meaningful directory on Windows. It should really be
os.path.expanduser('~'). To be honest it is probably always safe to
assume that os.getenv('LOCALAPPDATA') executes to something sensible
on any Windows system that hasn't been tampered with.
get_annotated_class_object is (sort-of) the inverse of execute_annotation,
so adding a get_annotated_class_object to implement execute_annotation
specifically for Tuples didn't make much sense.
The test here is a bit contrived, the actual place I found this
was in using a NewType as a type within a NamedTuple. However due
to https://github.com/davidhalter/jedi/issues/1560 that currently
also fails for other reasons. This still feels useful to fix on
its own though.
