The last time I tried async/await with Babel I had huge problem that my code was very hard to debug. When runtime error occurred it did not show any useful information, like error line number, and thanks to transforming and regenarator-runtime wrapping of my code, it was nearly impossible to step through the code in any meaningful way, so I had to fallback to console log driven development.

Maybe something changed since the last time I tried, or perhaps i mis-configured something? How are error messages and debugging with this plugin?
