What part of the semantics are you unclear about?  Two sequences are
equal if they are element-wise equal.  That is the definition that
people rely on, that's the definition that the interpreter uses, and
that definition is even consistent with the behavior you saw with the
self-referencing lists which for some reason surprised you.
