Manual rolling or other polyfills desired by the project.

IMPORTANT: When adding / removing polyfills, ensure that typescript becomes
aware of their existence, either by creating `src/typings/polyfills.d.ts`
and defining them there, or or by adding the appropriate field polyfill to the
`lib` property in `tsconfig.json`.
