Thanks for the tip. What's getting mangled?
When you start a new thread, your From: line is
One of your replies to Mark Hills put his address into the From: line.
I am no longer using a standard email program. When I reply to a message, I contstruct the reply by manually editing the message being replied to. I make mistakes when I do that. One of the mistakes I make is forgetting to update the From: address. I'll try to be more careful.
I'm trying to understand what primitive operators are built into hugs that are then used to load the Prelude. (I'm a bottom-up type of person).
I don't think that a bottom-up approach that goes through Hugs is the best way to learn Haskell (not that going through a compiler written in Haskell will be any better). You're better off taking the Haskell 98 Report as the baseline.
That is my plan. I expect to buy copies of the revised report and the Haskell Road to Logic,... book I got through interlibrary loan. The revised report is available online, but I find reading a physical book handy when I want to take a break from the computer.
(If you still have that Prelude.hs you copied in the current directory, you should remove it.)
What I still don't understand is why that file being present affects the way hugs runs when hugs says it is ignoring the file.
The explanation is in the above messages of Mark Hills and myself; I can't think of another way to express it. Basically you put an internal Hugs module where it wasn't expected. Just don't do that.
At some point I am going to fix that problem in my copy of hugs. Dave Feustel
