[Haskell-cafe] [Haskell] Haskell Weekly News: Issue 316

After doing more than 150 of these, I have come to the conclusion that

it is time for me to take a permanent break from HWN. I realize that

"we could do better", and have something a bit more edited than a

collection of links, and some quotes. I wish I had more time to devote

to such endeavour, but my time is currently being taken up by trying to

help my 1 year old explore her little world.

We owe Daniel a huge debt of thanks.  HWN is a huge service to the community. I have read many interesting blog posts that I would have never otherwise found.  Thank you!

We really need a successor!  Please, please.

Subject: [Haskell] Haskell Weekly News: Issue 316

Welcome to issue 316 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers
from January 18 to 31, 2015

After doing more than 150 of these, I have come to the conclusion that
it is time for me to take a permanent break from HWN. I realize that
"we could do better", and have something a bit more edited than a
collection of links, and some quotes. I wish I had more time to devote
to such endeavor, but my time is currently being taken up by trying to
help my 1 year old explore her little world.

If you'd like to be the one to continue the long tradition of HWN, drop
me a line.

Thanks for following along for the last 3 years!

   * hiptobecubic: benzrf, well sure. I'm not suggesting that lens has
     actually left any operators available for anything
