JSDoc @implements tag/clause not checked

// @ts-check

/**
 * @typedef Foo
 * @property foo {() => string}
 */

/**
 * @implements {Foo}
 */
class C1 {
    foo = () => {
        return 10;
    }
}

/**
 * @implements {Foo}
 */
class C2 {
    foo() {
        return 10;
    }
}

Expected: At least an error on C1 Actual: Neither of these error

I attempted this with a TS interface but was unable to get it working. ie:

interface Test
{
func(n: number): void
}

/** @implements {Test} */
class MyTest
{
func(n) // `n` is implicit any
{
}
}

EDIT: okay, so it technically does work (in that MyTest can be passed to things expecting a Test, and as long as you don’t re-declare it you will see the inherited type), but “func” doesn’t auto-inherit the documentation or type annotations. I think that’s a different issue though? maybe?

Workaround, based on this comment.

class MyStoreImpl {
  constructor() {
    // Verify that the class implements the interface.
    void (/** @type {import('./types').MyStore} */ (this));
  }
}
