Thanks for submitting the Trac bug. I don't know what the answer to
your qn below is, but maybe someone else on ghc-users does. Meanwhile,
I added the qn to the bug report.

The difference is subtle. The semantics of seq and pseq are
identical; however, GHC can see that seq is strict in both its
arguments and hence could choose to evaluate them in either order,

Yes, this is a highly desirable goal.
However, having said all that, arguably an exception should be made in

Dear GHC Hackers,
I'm using the GHC API for a project of mine. I have a question about the way
GHC 'desugars' the following overloaded function:
incL :: (Num a) = [a] - [a]
incL [] = []
incL (x : xs) = (1 + x) : (incL xs)
After calling 'Desugar.deSugar' on this function I get the
Hello,
I have a proposal for ghc. I think that it should take a new option,
say --make-command. This will specify a command to be run whenever a
source file is read in by ghc. The command will be passed an argument,
which is the name of the source file. The idea is that the command can
be used to
Hi
Just for completeness, I came up with a proposal that would solve all
this, but in a very non-cabal style way.
Taking an example of happy, every generated file (File.hs) would have
as its first line:
{-# ORIGIN happy sourcefile.y -options -to -happy #-}
Then you just modify all haskell
Hello,
I have a perl script which I call 'hsman', which indexes
Haddock-generated HTML files, and allows users to search for functions
and also GHC manual topics. For instance, I can run:
$ hsman foldl
to open the documentation on 'foldl'. There is also tab-completion in
zsh.
If people think
I would definitely like something like this.
like
{-# PREPROCESS drift-ghc #-}
to specify the file should be preprocced by drift-ghc.
