I am taking a Kotlin class at Coursera and in the interactive code challenges I see eq in list1.allNonZero() eq true, but when I copy code into IntelliJ I get unresolved reference. Is eq part of Kotlinlang or hidden extension in the course code?

That's really bad form... Hiding equals and comparing with boolean literals.

I hope it's just for demonstration purposes!

Yeah, its from the online code test. I copied it to IntelliJ without that key feature. But I must add I am impress over the EduTools integration with Coursera.
