List operator '|'

[DocThreeC]

I was just testing pyson with some examples, such as a variation of the blocks world, when I just realized that the '|' operator to deal with the "rest" of a list, when you are working with the head of a list for instance, is not supported.

Let's see if I understand the semantics. Let L = [1, 2, 3, 4, 5, 6].

(1) Then L = [A,B,C|D] is supposed to unify as A=1, B=2, C=3, D=[4,5,6]?
(2) Can | be used multiple times, e.g. L = [A,B,C|D|E]?
(3) Can , be used after |, e.g. L = [A,B,C|D,E]?

Will have to check how the Java implementation handles this.

We were interested in the (1) option, that was the one giving us error, but it is true that we were not considering the other two possibilities, and we don't know how the Java implementation deals them.

Thank you for the answers. We will be following your advances.
