I am currently trying to autogenerate .d.ts files for my JavaScript API using --declaration and I am running into problems. All of the files which use a const namespace have their methods and values duplicated. For example,

const Foo = {
      foo() {
        console.log("Foo");
      }
}

gets converted to

declare namespace Foo {
      function foo(): void;
      function foo(): void;
}

instead of

declare namespace Foo {
      function foo(): void;
}

Not exactly sure what is causing this issue and how to get about solving it. Any help would be much appreciated.
