I don?t understand: why can?t this mailing automatically set the ?reply-to?
field to beginners@haskell.org ? A lot of the other mailing lists that I?m
subscribed to do that... Is it a conscious decision or a technical limitation ?

Excellent question! I believe we're on mailman software and the list admin
is Benjamin Russell: dekudekup...@yahoo.com or beginners-ow...@haskell.org
I've cc'ed both to see if we can get a response from him.
It does look as if it's merely a config option:

So F(x=x0) has no meaning in itself? Only the differences
F(x=x1) - F(x=x0) have a meaning?

Thanks. It took me a while to fully understand what you said here.
