Absolutly. Every expression in Haskell denotes a value. Now, we've not agreed what "value" means, but to me it is a value. :)

It is one value, or several ?

It is one value with parts that are values themselves.

It is one value or a SET of values ? What are the parts ?

A set of values is again a value. So is a list of values. This is similar to C++ where a field of an object can again be an object. [1..] is a value of type [Int] and every element can be considered a part of this value. Best wishes, Wolfgang P.S.: Didn’t send this to the list in the first place. I don’t like mailing lists which don’t set the Reply-To: field.
