Now I also noticed I have this error from Figwheel lurking in the terminal where I started the REPL:

That’s weird. This certainly exists on master, I assume in happens when you’re testing with it, right?

I am testing with master, right.

No, sorry. Checking that again, that came when testing from the 0.6.0 branch.

But 0.6 doesn’t have such a method, so I wonder how a reference to it came into being.

It could have been me who didn't reload the server cleanly enough.
