1.1.384 forbids ellipsis defaults in NamedTuple stubs

[srittau]

Describe the bug

Cf. python/typeshed#12764. When trying to update pyright from 1.1.383 to 1.1.384 in typeshed, it reports NamedTuples that use ellipses as defaults:

class ToCPlaceholder(NamedTuple):
    render_function: Callable[[FPDF, Any], object]
    start_page: int
    y: int
    pages: int = ...

Causes:

/home/runner/work/typeshed/typeshed/stubs/fpdf2/fpdf/fpdf.pyi
/home/runner/work/typeshed/typeshed/stubs/fpdf2/fpdf/fpdf.pyi:97:18 - error: Type "EllipsisType" is not assignable to declared type "int"
"EllipsisType" is not assignable to "int" (reportAssignmentType)

Similar to function defaults, NamedTuples can have complex defaults that can't be represented statically in stubs and should use an ellipsis instead.

In [1]: from typing import NamedTuple
In [2]: x = 42
In [3]: class Foo(NamedTuple):
   ...:     a: int
   ...:     b: int = x
   ...: 
In [4]: Foo(12)
Out[4]: Foo(a=12, b=42)

This is #9189.

It actually isn't #9189, that is a separate issue. Please reopen, sorry for the churn.

Thanks for the bug report and apologies for the regression. This issue was specific to stubs, so it wasn't covered by pyright's unit tests.

This will be addressed in the next release.

This is addressed in pyright 1.1.385.
