Repro for:

developit/microbundle#808

Steps to repro:

1 - Well, clone this repo...

2 - Install pnpm on your machine if you don't have it

3 - Use pnpm to install dependencies by running pnpm install at the root of this project (you only need to do this once, the package dependencies will also be installed)

4 - Now go to the package under packages/some-package and run pnpm build

You should get this:

(babel plugin) SyntaxError: absolute-path-to\bundle-bug-repro\modules\code.ts: Unexpected token, expected "," (2:38)
