Summary: hiding does not follow haskell report
Initial Comment:
Email: [EMAIL PROTECTED]
As understand hiding from the Haskell report, it should
hide only the unqualified name and not the qualified name,
e.g., hide head but not Prelude.head (or List.head). This
is not the case with ghc 6.0.1:
[EMAIL PROTECTED]:/bug-2111> cat Main.hs
module Main where
import Prelude hiding (head)
main = do print (Prelude.head [0..])
head
head = print "head"
[EMAIL PROTECTED]:/bug-2112> ghc --version
The Glorious Glasgow Haskell Compilation System,
version 6.0.1
[EMAIL PROTECTED]:/bug-2113> ghc -fglasgow-exts -o Main --make Main
Chasing modules from: Main
Compiling Main ( Main.hs, ./Main.o )
Main.hs:5: Variable not in scope: `Prelude.head'
[EMAIL PROTECTED]:/bug-2114> ghc -o Main --make Main
Chasing modules from: Main
Compiling Main ( Main.hs, ./Main.o )
Main.hs:5: Variable not in scope: `Prelude.head'
[EMAIL PROTECTED]:/bug-2115> runhugs Main
0
"head"
as expected.
