First of all I want to congratulate you to beat everybody on implementing modules, because of this I am using Safari 10.2 now to develop my webapplications.
I currently have two issues,
1) I don't seem to get source maps working in the debug tab?
demo https://mollie-api-go.appspot.com
source code https://github.com/gertcuykens/mollie-api-go
2) Is it possible for you to collaborate with TypeScript to have a consensus on the import convention
see https://github.com/Microsoft/TypeScript/issues/14861
3) Can't copy text from the console output pannel to the clipboard
