why does this not run, but test1.equals(test2) does?

[karelpeeters]

Because the equals signature must accept anything but that doesn't mean it actually makes sense, so they added an extra useful check for ==.

[karelpeeters]

There's a similar story around the contains operator.

Btw, @svtk's Kotlin for Java Programmers on Coursea is awesome too.
