描述

declare class C {
  private static implicitAnyTypeProperty;
  static inherited: typeof C.implicitAnyTypeProperty;
  inherited: typeof C.implicitAnyTypeProperty;
}

expected:

$ node_modules/.bin/tsc index --noImplicitAny
index.ts(2,3): error TS7008: Member 'implicitAnyTypeProperty' implicitly has an 'any' type.

actual:

$ node_modules/.bin/tsc index --noImplicitAny

研究方向
Investigate the TypeScript checker's handling of private static properties in the context of noImplicitAny. The issue likely lies in the checker's logic for determining implicit any types for class members, specifically private static properties. Review diagnostic reporting for property declarations in `src/compiler/checker.ts`. Check for any recent changes that might have affected this behavior.
