NodeList-traverse why first() and last() return NodeList?

[Les]

I was expecting first() or last() would return the node, not a NodeList?.

[James Burke]

first, last, odd and even are meant as replacement calls for the type of group pseudo selectors you can do in jquery but not dojo. So, in jquery, you could do $("form:last"), in dojo, you can do dojo.query("form").last().

Ideally we could get those group pseudo selector support into the dojo query engine, but this is a stop-gap until then. As with methods like .at(), we return a dojo.NodeList? for the calls, not single nodes, so normal chaining will work.
