The pipe operator in prolog returns one or more atomic Heads and a Tail list.

?- [a,b,c] = [a,b|[c]].
true.

Nesting multiple pipes in a single match can be done similar to this:

?- [a,b,c] = [a|[b|[c]]].
true.

What does the statement [a|b|c] infer about a, b and c?

I was wondering, I am aware you can use assert to add facts or rules or whatever if you have declared the predicate to be -:dynamic, but this only allows the changes that are made to be kept in that session only, e.g. if you close the prolog window then the database changes are lost. So I was wondering… >>> More
