WIth 6.10.4 there's a major bug with Snow leopard: It doesn't work
(Cannot compile 64-bit).
Is this fixed in the new release?

Hello everyone,
Could a new mailing list for patches and/or commentary do the work of
the proposed package Wikis? Similar to the libraries list but separate
so it doesn't pollute the libraries list from its important job of
discussing and refining the core libs.
From my perspective, mails have

Both of these refer to many “haskellers” – no apostrophe should be
English, while my first language (and in fact, only language...) is
also my worst language... Thanks for catching the grammar snafu.
While I'm here, please note that the issue number is off as well, it's
fixed in the version on sequence.complete.org, but not in the email

Hi!
This technique has been used to define netlists in hardware description
languages. The original Lava [1] used a monad, but later switched to
using observable sharing [2]. Wired [3] uses a monad similar to yours
(but more complicated).
I think it would be nice to have a single library
What does Haskell need to be saved from?
(Its growing popularity and mushrooming library?)
Arguably John Earle's emails suggest that the answer to this is Yes.
