I got the same error on ubuntu precise with GHC 7.10

Seems to be related to https://github.com/phonohawk/HsOpenSSL/issues/36 (and `--allow-newer`)

Seems it's out but `changelog.md` misses an entry?

Also there aren't tags for any `0.12.x` neither `0.13.0.0` releases.

How's about: if it cannot be guessed, then could it be configurable?

I tried to build `angel` with stack (relatively old `all-cabal-hashes`, so doesn't see the edit yet): ``` % stack --resolver=nightly-2016-11-11 install angel configurator-0.3.0.0: download configurator-0.3.0.0: configure configurator-0.3.0.0: build configurator-0.3.0.0: copy/register...

We have `both` in `lens`. We could had it in `Data.Bitraversable`, but not sure it worth the trouble. ```haskell join bimap bothmap ``` Former is not much longer, is it?

I see, so https://www.sciencedirect.com/science/article/pii/S0890540109002405 has a mistake, what they call left is actually right. (compare to e.g. https://en.wikipedia.org/wiki/Module_(mathematics)) - André Hirschowitz, Marco Maggesi: *Definition 8 (Left modules). A left R-module...

Wait. Isn't it that `m` is the right module of `t m`. We have `t m (m a) -> t m a`. As I said, it's confusing.

 R = `m`, M = `t m`. Who is wrong, Maggesi or nLab ?
