Who knows, please, how to work with the program of
main = interact (\ s -> shows (read s :: Bool) "\n")
in the interpreter ghci ?
This is on ghc-cvs-6-4-branch-June-15-2005
under Debian Linux, i386-uknown.
When compiled, it works: > ghc --make ReadBug
> ./a.out
> True press Enter
> press Control-d
> True
And it does not work under ghci:
--------------------------------------------------
> ghci ReadBug.hs

Compiling Main ( ReadBug.hs, interpreted )
Ok, modules loaded: Main.

*Main> main
True

Is this a GHC bug?
