	I think that insofar as this is a problem, we should fix it by ~~rewording~~ the task. ~~Languages~~ ~~may~~ ~~differ~~ on whether ~~they~~ ~~have~~ null ~~pointers~~ or ~~pointers~~ to null, ~~but~~ ~~that~~ ~~doesn't~~ ~~affect~~ ~~the~~ ~~patterns~~ of ~~usage.~~ --[[User:Kevin Reid\|Kevin Reid]] 22:42, 5 August 2008 (UTC)		I think that insofar as this is a problem, we should fix it by changing the task, not the examples. The basic idea of null is similar enough for this collection to be informative, whether the language has everything-is-a-reference-including-null (Python), maybe-null references and primitives (Java, C), type systems which can include or exclude null (Common Lisp, E, C#), or data structures which explicitly add a case (Haskell) --[[User:Kevin Reid\|Kevin Reid]] 22:42, 5 August 2008 (UTC)
