Unused declaration in Iteration/Format cause TS build error

[selfrefactor]

🐞 Bug Report

Describe the bug

The original issue is selfrefactor/rambda#511

I am using ts-toolbelt but I ship part of its code within my library, so users receive full TS support out-of-the-box. The unused part IMap extends Map = NumberMap causes TS build error with following TS config:

"compilerOptions": {
        "noUnusedLocals": true,
        "noUnusedParameters": true
 },

Reproduce the bug

Repo: https://github.com/selfrefactor/rambda-tree-shaking

Folder: packages/rambda

Command: yarn build

Expected behavior

Build process completes with no errors.

Possible Solution

Remove the unused code.

So again, there are unused variables that causes problems for me. Is there a way to add such check, so I don't have to trouble you every time?
