llvm dev - Jan 2017 - LLVM Weekly - #157, Jan 2nd 2017

I want to second Andrey here and then some.

I think it is very easy to lose sight of how valuable the work you're doing
with the LLVM weekly summaries is to the community. The new year is a great
time to reflect on that and I want to add my voice of support and thanks.

I think this kind of newsletter is one of the only ways the community can
continue to scale.

Please reach out for assistance at any point if folks in the community can
do more to help support this effort. Speaking for myself at least, I'm more
than willing.
