Just add it next to -Wall wherever you‘re setting that, because I think you
must be setting that yourself somewhere (it’s not on by default).

Ah good point :) Wonder if I can change it on cabal file somehow.
Thanks
Hello Haskellers!
Is it posible to create instance of MonadBaseControl IO (ConduitM i o m) ?
This would give a great posibility to catch exceptions just inside the
ConduitM monad with lifted-base package. And more, http-conduit's
`withManager` restricts base monad (which must be base for
You can also do this on a module basis with {-# OPTIONS
-fno-warn-missing-signatures #-}. I prefer adding type signatures even for
cases where I don't think it's important. GHC spits them out so almost no
time spent, and someone might find it useful at some point.

Wait... what do you mean Core cannot generate new names to be exported.
I meant if I add a new name in the Core transformation, that doesn't
change the module's export list as seen by everything outside that
module. Which makes sense, it just means I have to change my approach.
Maybe you mean
Is there a definitive list of things in GHC that are unsafe to
_compile_ if I were to take an arbitrary module and compile it?
E.g. off the top of my head, things that might be dangerous:
* TemplateHaskell/QuasiQuotes -- obviously
* Are rules safe?
* #includes — I presume there's some security

Whatever guarantees GHC offers (e.g. using Safe Haskell), I would always
run things like these in a sandbox. It's much better for security to
dissallow everything and then whitelist some things (e.g. let the sandbox
communicate with the rest of the world in some limited way) than the other
way

No, it is not, for approximately the same reason that you cannot create one
for ContT (or any form of continuation).
