Tuple basics

[Sam Hu]

Hi,

I seached questions regarding Tuple in this newsgroup but did not find the the same question I have.Since I am a newbie ,they are too advanced to me at this moment.My question is just :What is tuple?what can tuple do in D while  other languae like c++ can not do or can not do well?Could somebody please post a very simple code segment and an simple but enough explanation so that I can understand what the hell a tuple is .

Thank,
Sam
