Object result of import all from module has no index signature

[OliverJAsh]

TypeScript Version: 2.3.4

Given an actions module where each exported member satisfies the type type MyFn = (...args: any[]) => any, when I collect those exports using import *, the resulting object has no index signature, leading to unwanted type errors.

Code

import * as actions from 'actions';
type MyFn = (...args: any[]) => any;
type MyMap = { [key: string]: MyFn };
const myMap: MyMap = actions;

Expected behavior:
No error.

Actual behavior:

Type 'typeof "/Users/OliverJAsh/Development/unsplash-web/app/actions/index"' is not assignable to type 'MyMap'.
  Index signature is missing in type 'typeof "/Users/OliverJAsh/Development/unsplash-web/app/actions/index"'.

One workaround is to spread the object:

import * as actions from 'actions';
type MyFn = (...args: any[]) => any;
type MyMap = { [key: string]: MyFn };
const myMap: MyMap = actions; // error
const myMap2: MyMap = { ...actions }; // no error!

Just ran into the same problem. Thanks for the workaround.
