Your example uses isset(), which is valid code in most circumstances, but as you said it's not particularly good code. Do you have other examples that come to mind ?

There is plenty of code out there in the real world that is not particularly good, so I think it's a realistic example to think about. The question is, do we think the language can and should help people avoid that mistake? - Would the explicitness of "use(...)" make it more likely someone would spot it? - Would people be more likely to write "let $guest=..." (or whatever block-scope keyword we choose) than add "$guest = null;" at the beginning of the closure? I'm not totally sure, but we should always consider the impact on less-expert users, not just the power-users who are the ones often asking for new features. Regards, -- Rowan Tommins [IMSoP]
