pear won't compile with recent versions of nightly

[cdaringe]

hi all. sorry if this is a non-issue for this lib, but i'm new to rust and still learning its quirks. it seems there are more than expected :$.

i get the following errors when running cargo check w/ rocket 0.3.[3|4]:

Looks like this might be breakage introduced by today's nightly. I'll take a look shortly. In the meantime, can you try using yesterday's nightly and see if the issue resolves? You can do this via something like 'rustup default nightly-2017-12-16'.

I have the same issue. Using nightly-2017-12-16-x86_64-unknown-linux-gnu fixes the issue.

Fixed in 0.0.12.
