Note the colon before the name... that is what causes the remote
branch to be deleted. My understanding is that you are literally
pushing a void local branch over the remote branch, which effectively
deletes it.
Since Git 1.7, I believe you can also:
git push origin --delete origin/wip/new-flatte
I believe you do this with: arc patch D123456

Instead of encoding the status in the URL, since we don't want URLs to

I think the fact that we now have these minimal installers floating

I personally just download the latest bindist from the GHC site and

HERMIT has some code for building dictionaries for a given predicate
type (by invoking the typechecker functions that do this):

Sorry, I dropped the ball on creating a ticket. I just did so:
https://ghc.haskell.org/trac/ghc/ticket/10829
(As an aside, the original ticket, #10528, had a milestone set as
7.10.3, so I just assumed a 7.10.3 was planned and coming soon.)

As you mentioned, the two show stoppers for HERMIT are #10528
(specifically SPJs commit in comment:15 - see [1]) and #10829 (see
D1246). The first disables inlining/rule application in the LHS of
rules, the second does the same in the RHS. nofib results for the
latter are on the ticket.

Simon,
I really enjoyed reading this paper... I was wondering if you could comment
on the implementation of Strict Core? Was it ever implemented in GHC (even
as a proof-of-concept)? If not, was it just due to a lack of time or some
fundamental limitation or problem discovered after the paper? If i

I'm guessing this is the same problem with gmp on OS X, but I got it
during the ./configure step, so thought I'd pass along the error

I've also been trying to find a good way to do this. I had a somewhat hacky
driver that would use GHC to compile the plugin in a temporary directory,
then create a custom package database with only that plugin and add that
database to the stack of package databases when compiling the target

+1 for pragma, though the SPEC type is always the same anyway... is it
exported from somewhere? It seems silly that I have to define and annotate
my own version when I want to use it. I realize that doesn't solve your
stage 1 problem... more of just a general question.

Wouldn't #2 mean we'd have to annotate (via pragma) every type we want to
eliminate, rather than a single type?
I think the current design serves the need: "I want you to try really hard
on this function." ... which seems useful.
#2 seems like an orthogonal issue: "I want to ensure this type is o

I know that #7602 has been mentioned as a final loose end in the RC. I was

how it effects GHC users.

Somewhat related: Using Hoogle with +ghc will give results which link
into the ghc haddock docs.
For instance: http://www.haskell.org/hoogle/?hoogle=%2Bghc+getOccName

Are all of these links collected on the GHC wiki somewhere? If not,
would you mind adding them?

At the risk of sounding redundantly redundant, I'd like to third this.
My workflow for finding stuff in the GHC codebase is a mixture of grep
and Hoogle. Searching Hoogle for "+ghc :: [TyVar] -> Type -> Type" is
a huge timesaver, and Hoogle sends me to the generated haddock
comments. Usually the h

Minor point, but you can use "git blame -w"
mkVarUnqual calls mkVarOccFS, which constructs an OccName in the
varName namespace. You need to construct your RdrName via mkTyVarOcc,
which picks the Type/Class namespace.
