This is similar to #2602.

@bojand I can think of 2 possible ways to implement this functionality: * Add the option to pass another parameter to the action, specifying the domain. (e.g. `mailgun.messages().send(data, newDomain, callback)`)....

It's been a while, but I remember correctly, the use case was simple. I wanted to be able to add milliseconds to a date.

Correct, but if I want to add other parts as well, it would require a call to `.add()` and then to `.addMilliseconds()`.

>Bundlers usually don't compile files in node_modules. I'm not sure what you mean by that. The whole point of a bundler is to bundle your code along with the libraries...

Also, unless Rollup has a way to bundle the type declaration files as well, we need to publish the unbundled ES6 sources along with the type files.

@rtheunissen What are your thoughts about this?

@phifa I believe Webpack is overkill for a library like Pjax. Webpack is more suited for a webapp with different types of assets or multiple entry points. For Pjax, Babel...

Do we even need Rollup?

True. I'll have to look into the differences between Rollup and Browserify.
