Friends
I'm looking for someone, or a small group, to act as a Supreme Being for
Template Haskell. Might you be willing?
There is a steady trickle of bug reports / feature requests relating to
Template Haskell, which I find that I simply don't have the time to pay proper
attention to. Here is
Done, at TemplateHaskell/Status.
If any dev out there has plans for changes to TH, please link to these changes
from TemplateHaskell/Status. I don't believe there are any currently afoot, but
please do correct me if I'm wrong.
Thanks!
Richard

Hello *,
What?

We (see From: CC: headers) propose, plain and simple, to turn the
currently defined type-synonym
type FilePath = String
into an abstract/opaque data type instead.

Main.hs:17:26: error:
Couldn't match type ‘[Char]’ with ‘()’
Expected type: Proxy () String () X IO ()
(aka. Proxy () [Char] () X IO ())
Actual type: Consumer String IO
I can't even see what performance number has changed, because
harbourmaster only shows the tail of the log.
From https://phabricator.haskell.org/harbormaster/build/4553:
10 bytes allocated value is too high:
11 Expected haddock.Cabal(normal) bytes allocated: 6710234312 +/-5%
12 Lower bound
Thanks Richard, that's great.
How about starting a Template Haskell status wiki page, along the lines of
https://ghc.haskell.org/trac/ghc/wiki/Status/GHC-7.12.1
* The lists of tickets on these status pages are auto-generated, so you
could do the same to list open TH tickets.

Hello,
I'm trying to run code that works with ghci 7.8.3 under ghci 7.10.1
but this fails.
Under 7.8.3, when I run from the shell:
export LD_LIBRARY_PATH=thepath
ghci -lmylib -fno-ghci-sandbox mydriver.hs
I see the usual startup diagnostics along with

Hi Simon,
I'm happy to take this on. Through `singletons`, I am a heavy TH user and know
that end of GHC well.
The one caveat I offer is that I vastly prefer to chunk up similar bits of
work, and generally intend to let TH tickets languish until I sweep them all
up, somewhere near the planned
