Declaration file for function-module (TypeScript)

I use a node module that's not found by typings and doesn't exist in definelytyped.

the basic use of the module is:

import * as someFunc from 'some-module';

someFunc("some string");

As you can see, this module exports a function as its default. I haven't figured out how to write the declaration file for it.

This is the best I managed to do:

declare module 'some-module' {
    export default function someFunc(someArg: string): void;
}

BTW it does work JavaScriptly. It's only the TypeScript bothers me.

Any ideas how to solve that?
