Broken on most recent nightly

I seems like proc_macro_hack broke. Please use rustup override set nightly-2019-08-15 in the meantime.

    = note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)

I think this has been fixed in rust-lang/rust#63667

Though not yet fixed in the latest nightly:

This has been fixed as of rustc 1.39.0-nightly (4cf767307 2019-08-18).

Doesn't work with that version either:

@synul you need the toolchain one day newer, 2019-08-19 (built 2019-08-18). You were using 2019-08-18, built on the 17th.

Ah, indeed, the newest version works. I updated my PR with the newer version, not sure if that is still needed though...
