Regardless of what the report says (I can see why Hugs choose to
deviate), the problem here is really that there's presently no way for
the Haskell programmer of changing the echoing of a terminal attached
to a Handle. Adding the following two operations to IOExts would help
setEcho :: Handle

Hi,
yes, to compile ghc from Haskell sources you need a recent version of
ghc installed. ghc-2.10 is the default, see section 6 of the

Thanks for the report - the bug should now have been fixed (and a

The fix makes a couple of programmer visible changes. For instance,
in the name of robustness, SocketPrim.inet_addr is now an IO
action. Have a look in

Looking out of the panorama windows here at GHC HQ, the general
opinion seems to be that the grass is distinctly greener on the other
side, so we'd more or less agreed on changing "trace" to behave as
the Hugs version do! Since we're both willing to change, perhaps we

Yes, Green Card doesn't understand qualified type names in %fun
lines, hence that sorry hack. Compile your .idl with
-fno-qualified-names and hope that this generate any clashes with

For people that keep track of the fptools/ sources via the CVS

I believe this bug has been fixed. ghc-current, which is available on
the ftp site in source form, compiles the offending code without any
problems.

Thanks, got it. It looks as if it's seq'ing that's causing the

Hi,
this will not work, I'm afraid. That ghc-2.10 binary release was

Hi,
what version of ghc did you compile your program with? Based on your

implementation in the Prelude any longer), and I'm unable to reproduce

using list comprehensions for the kind filter&map operation you're
wanting to express, seems like a good option.
border p = check "no border in page" [ x | (Border x) <- p]
margin p = check "no margin in page" [ x | (Margin x) <- p]
check :: String -> [a] -> a
