Profit from Tree Shaking in Ramda in Webpack #2355

Hello, guys!

During my experiments with Tree Shaking in Ramda I found that the maximum profit I can get from it is the reducing a bundle on about 7Kb.

I'm wondering, is this because of the dependencies in Ramda or because of Webpack, or something else?

Here is how I tested it.
I created a file with the next code

import * as R from "ramda"

R.identity()

And compiled it two times:
with ramda@0.24 the size of the bundle was 59.2 kB
and with ramda@0.25 - 51.2 kB.

In my real project, where I did the same experiment, four bundles that use Ramda decreased their size on about 7Kb.

On the other hand, when I imported identity function directly from the source file, like this:

import identity from "ramda/src/identity"

identity()

size of the bundle was only 916 bytes. That kinda result I was expecting from Tree Shaking.

Code and Webpack configurations I uploaded to this repo:
