External Runtime Helpers

[knpwrs]

I've done some Googling and some searching around this issue tracker and couldn't find anything, so please excuse me if this has been discussed prior.

I was wondering if there were any plans to possibly introduce the ability to externalize helper functions non-globally. For example, how babel-plugin-transform-runtime does it. They import helpers from the babel-runtime package. In Typescript there is the --noEmitHelpers option but as far as I'm aware that requires putting the helpers in the global scope e.g., with the typescript-helpers package.
