What... is that deprecation warning?

Thanks for the report.

Likely a duplicate of https://github.com/JuliaLang/julia/issues/26516 Edit: The deprecation warning that is, not the failure :)

Yeah, the .= depwarn is rough. I'd be very surprised if that's still in place (at least at the repl, but even in general) upon release of 0.7. I'm imagining the uninitialized discussion on Discourse x10, all to support a pretty rare use case.

I'll try to fix this one right now. Let me know if somebody else is already working on a fix.
