Should ast.Match and ast.TypeAlias be exported from "_ast.pyi"?

[hunterhogan]

In "ast.pyi", I count 124 class definitions that are either class AST or a subclass of

• _Slice
• AST
• binaryop
• boolop
• cmpop
• excepthandler
• expr_context
• expr
• mod
• operator
• pattern
• stmt
• type_ignore
• type_param
• unaryop

and the class does not have the @deprecated decorator.

ast.Match is defined as a subclass of ast.stmt.

ast.TypeAlias is defined as a subclass of ast.stmt.

This suggests they should be imported from "_ast.pyi"

However, ast.Match and ast.TypeAlias are not in "_ast.pyi" and I count 122 classes: 2 less than I expected.
