Test suite failure with GHC 8

[snoyberg]

This is due to hlint failing, I'm not sure if it's related to GHC 8:

Oi, strange. I thought I told hlint to ignore eta reduction warnings, though.

I'll take a look. I need to do a release of 0.6.0.0 with newer documentation and fix up the CI to include 8.0.1, etc.

I haven't seen this with GHC 8.0.1 or anything, and as I said, I told HLint to ignore eta reduction warnings, so maybe this is just a random ghost?

Closing, due to inability to reproduce.
