Hi,

module ZipTyEnvBug where
type A i = i
type B = A

Folks,
my code has unwillingly been forced to read a large string generated
by show. This turned out to be a robustness test because the effect is
a stack overflow (with Hugs as well as with GHC) and, of course, this
error happened in a CGI script.
If you want to try the effect yourself, just
Hi all,
I'm sending this to the whole list because maybe there are others who are
doing the same thing as me, and so it would be useful to share some
effort.
What about a standard AST format? What about static analysis and
type checking/inference?
A few of us at Melbourne have been

I'm pretty sure he did, but he can speak for himself. I know he

I'm afraid that I have very little faith in the numerical analysis
expertise of the typical Haskell implementor, so I think it is dangerous
to give them an incorrect default implementation. I am reminded of
the notorious ASCII C (very)-pseudo-random number generator . . .

I am happy to announce the first release of popenhs, version 0.00.
popenhs is a very small Haskell library, based on runProcess
in hslibs' posix library. It provides lazy output from
subprocesses through two functions popen2 and popen3.

hi.
I'm trying to run an system command (wget) within a CGI script and get the following
error:
Exitfailure 127
How can I get more information out of an ExitFailure x error?
Can I use ioeGetErrorString? But this function doesn't work on ExitCode, which system
returns.
TIA
