I see that when I post to the Haskell lists (
http://www.haskell.org/mailman/listinfo) from gmail, the end of my post has:
"-------------- next part --------------
An HTML attachment was scrubbed...
URL: ..."
The url seems to be a copy of my mail.
I can't seem to find the appropriate setting in gmail to avoid this. (Or is
it one of the mailing list settings a subscriber can adjust?)
Can someone offer a tip?
Thanks much,
-- Peter

i have downloaded data from postgresql into a file my haskell program.
i can of course edit this file with say vim.
can i run vim on that file from within haskell and after quiting vim
have control returned to my haskell program?
the situation is like calling vim to edit my claws-mail emails instead
of using the native editor. after editing, i quit the external editor
and am returned to the native editor.

Right, that is (slightly) cleaner than using my "show" trick below.

Alternatively you could define your own enumeration type:
data SchemeType = NumberT | BoolT | AtomT
deriving Eq
schemeTypeOf :: SchemeVal -> SchemeType
schemeTypeOf v = case v of
Number _ -> NumberT
Bool _ -> BoolT
Atom _ -> AtomT
typeChecker = Data.Function.on (==) schemeTypeOf
C.

Hi all,
Thanks for the many replies. I have been looking at the Template Hakell route
(thanks Brent). It looks like it's going to take a bit to figure out how to use
it properly (a lot of the tutorials/docs seem a little out of date?), but
should do the trick once I do.
Thanks again to everyone for their replies.
Matt

Yes, unfortunately, the available tutorials/docs on Template Haskell
leave a bit to be desired. Just keep playing around with it, and
you'll pick it up relatively quickly.

In gmail, on the toolbar right above the message, there's a button for
"plain text". I think that will do the trick. If you don't see "plain
text", but you see "rich formatting", then you're already in plain
text mode. When you're replying to messages from the mailing list,
you'll be in plain text mode by default. It's only when you start a
new message that you need to do this.

Not very important but, I don't think this is the case. At least not for me.

Other than slicehost, here are some more VPS hosting options, in USA.
