Same. I haven't looked at the patch yet, but I like how clean (and
limited in scope) this is.

Levi, what's the syntax like for closures with use blocks? I can see
that looking a bit weird either way, since it's presumably either:

function ($foo): Bar use ($quux) {}

or:

function ($foo) use ($quux): Bar {}

Neither are exactly ideal, but that's the hand we've dealt ourselves, I gue=
ss.
