Tree shakeable static methods (using rxjs and lodash in alongside)

I want to use rxjs and lodash or ramda in the same project.
I am using typescript with ECMAScript module import statements. (In an ionic project with webpack as the module bundler)

rxjs

lodash

ramda

webpack

rxjs and lodash-es propagate import statements like this, to enable tree shaking:

rxjs

lodash-es

import { map } from 'lodas-es'
import { map } from 'rxjs/operators


As you can see, this approach has two problems:
Name clashes (I could use an alias, but I think this will lead to more confusion)
Very general method names like map, filter etc. are in both libraries present and you always have to look in the import statement, which one is meant and where it came from.

map

filter

The static method approach is much more readable in my opinion, because it is so explicit.
I want to keep the syntax like it is in commonjs and also enable tree-shaking. Is this possible somehow? Which alternatives do I have here?

// commonjs
const _ = require('lodash')
const Rx = require('rxjs')

_.filter()
Rx.Observable.from([1,2,3]).pipe(Rx.filter())

// esmodule (this does not work, but I would like to use it this way,
// with tree shaking enabled)
import _ from 'lodash'
import Rx from 'rxjs'


I am not sure if this prevents tree-shaking, but you can do import * as Rx from 'rxjs' and import * as _ from 'lodash', and access functions with Rx.map(...) and _.map(...)

import * as Rx from 'rxjs'

import * as _ from 'lodash'

Rx.map(...)

_.map(...)

I'm pretty sure "god objects" like _ and Rx are exactly what prevents tree shaking.

_

Rx

Use aliases. It is not confusing if you choose sensible aliases. How about import {map as _map} from "lodas-es"; and import {map as rxmap} from 'rxjs/operators'

import {map as _map} from "lodas-es";

import {map as rxmap} from 'rxjs/operators'

On the other hand: Importing lodash if you already use RxJS seems counterproductive if your goal is to minimize size. map is even built in JavaScript btw.
