[Haskell-cafe] hyperloglog build error

[Konstantine Rybnikov]

Hi!

I wanted to use hyperloglog [0] package, but got these errors:

https://gist.github.com/k-bx/70654962d4d98ee52e22

I am now trying to "match by hands" why that instance doesn't exist for me,
but maybe some of your could help, since I'm far away from all near-lens
libraries (but I promise to learn those!).

Thank you!
