[email protected] is unsupported for this version of jspm

[adriatic]

Just tried to rebuild demo-kendo and observed this warning [email protected] is unsupported for this version of jspm.

Two questions:

1. Why are we still using core-js? Rob announced a year ago that Aurelia does not depend on it any more.

2. What is really the meaning of this error message? Is it the consequence of us locking jspm to a specific version - which in turn does not support [email protected]?

Its been so long since I thought about it, but it's because we use in-browser transpilation (we transpile samples written in ES6/ES7 at runtime), and babel-runtime needs more of core-js that is not in aurelia-polyfills.

Yes, although it works pretty well for not being supported

Thanks - makes sense and then I am happy 😄
