It seems that there is some issues with the 0.9.37 core-js package and tsc 2.2.1

I get a lot of compiler errors: (just a clipout of them)

With the 0.9.35 everything works as expected.

I am wondering if it is the change in ts.config from es5 to ef2017 that causes this? Can't really see that any of the other changes could have done this?
