That's what I thought, but:
"If you mark "make" as explicitly safe, then it works."

So there's a loophole somewhere here.

Also related, I think it is a flaw that the very *signature* of something is
unsafe. In particular, the "array vararg" signature is *also* the one chosen
when you pass an array, which is perfectly defined and safe behavior...
