Hello and thanks for the d.ts file for lodash.

Unfortunately I don't get the following piece of code (simplified) to compile:

let collection = {
    a: '1',
    b: '2',
    c: ''
};
 _.some(collection, (value, key) => {
    return false;
});

=> Error:(186, 17) TS2345: Argument of type '{ a: string; b: string; c: string; }' is not assignable to parameter of type 'List<{}> | Dictionary<{}> | NumericDictionary<{}>'.
Type '{ a: string; b: string; c: string; }' is not assignable to type 'NumericDictionary<{}>'.
Index signature is missing in type '{ a: string; b: string; c: string; }'.

IMHO that should work according to their documentation (https://lodash.com/docs#some)

collection (Array|Object): The collection to iterate over.

The _.forEach method accepts an object (since it is declared as T extends {})

_.forEach(collection, (value, key) => {
    // do something
});

forEach<T extends {}, TValue>(
    collection: T,
    iteratee?: ObjectIterator<TValue, any>,
    thisArgs?: any
): T;

What is your opinion on that issue? Am I missing something?

Thanks for your help.

PS: I know that it used to compile with an very old version of the lodash.d.ts file (commitID: 9ce3cd4)
