[Haskell-beginners] inserting tupels inside list as tupels in list

maybe the subject is a little bit confusing :p I have a organiser list like that and have to add events (like panic, xmas, ...) which is also a type of tupel for a specific date: aliceOrg = [ ( (21,Dec,2009), [panic,aliceBDay] ) ( (25,Dec,2009), [xmas] ) ( (10,Jan,2010), [bobBDay] ) What function(s) can I use to add these nested lists and tupels here? -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/chbrowser
