| public boolean | hasLastCall()Returns true if this expressions contains a call to last()
return (_left.hasLastCall() || _right.hasLastCall());

| public boolean | hasPositionCall()Returns true if this expressions contains a call to position(). This is
needed for context changes in node steps containing multiple predicates.
