Anyone who thinks that Hugs' diagnostic messages are unsatisfactory
should try the following snippet with GHC: :-)
-----------------------------------------------
module Foo where
import Posix(fdToHandle)
bar = fdToHandle ``0'' -- ``0'' should be: (intToFd ``0'')
-----------------------------------------------
panne@liesl:~ > ghc -fglasgow-exts -syslib posix -c Foo.hs
panic! (the `impossible' happened):
ERROR: ``literal-literal'' not a single-constructor type: 0; type:
PosixUtil.Fd{-rD4,j-}
Please report it as a compiler bug to [EMAIL PROTECTED]
-----------------------------------------------
In the real program the ``0'' was actually something more complicated,
of course.
Cheers,
Sven
P.S.: The "lookupBindC:no info!"-bug from Feb 22nd is still in
yesterday's GHC... :-(
