[alexcrichton]

could you add a comment here that this isn't an integer?

[alexcrichton]

Nice! Thanks @mneumann! Looks like there's some CI failures as well?

If you're interested, I'd be totally fine adding a dragonfly builder on Travis via QEMU (there's some instructions in the ci folder) as well!

@alexcrichton : Thanks for the suggestions! Regarding CI, I am pretty busy with my thesis atm, but once I finish, I will take a look. This is definitively something we want to have!
