import member from export as namespace library does not import types

[cwmoo740]

TypeScript Version: 2.3.3

Code

import { createSelector } from 'reselect';
/*
 * changing the import to
 * import * as reselect from 'reselect';
 * and accessing reselect.createSelector fixes the issue
*/
export interface State {
    a: string;
    b: number;
}
export const selector = createSelector<State, string, number, { out: string }>(
    state => state.a,
    state => state.b,
    (a, b) => {
        return {
            out: `${a}+${b}`
        };
    }
);
console.log(selector({ a: 'string', b: 5 }));

outputs this index.d.ts:

export interface State {
    a: string;
    b: number;
}
export declare const selector: Reselect.OutputSelector<State, {
    out: string;
}, (res1: string, res2: number) => {
    out: string;
}>;

Expected behavior:
The output .d.ts file will include an import for the relevant type from 'reselect'.

Actual behavior:
The output .d.ts file attempts to access Reselect as a global namespace. Any downstream consumer that imports from this code will error.
