DefinitelyTyped Lodash

Question

I want to import single function from lodash while preserving typings. Such as this:

import invokeMap from 'lodash/invokeMap';

But it seems that I cannot do so. Compiler says that there is no module lodash/invokeMap. It's correct — DefinitelyTyped declares only top-level module for lodash, so I can import only the whole package. But I want to import only one function.

Is there a way to import only typings information about lodash without importing lodash itself?

Below is my workaround plan. I want to use standard CommonJS require function to import the necessary function without types information and then cast type onto it:

declare var require;

var invokeMap: _.invokeMap = require('lodash/invokeMap');
               ^^^^^^^^^^^
               Here I want to cast proper type from DefinitelyTyped,
               but how to reach that `invokeMap` typings alone?

With the current typings lodash this should work as you tried it before:

import invokeMap from 'lodash/invokeMap';

just install a current version of the ambient dependencies like so:
