haskell - Are infinite lists useful for any real world applications? -

-

i've been using haskell quite while now, , i've read of real world haskell , learn haskell. want know whether there point language using lazy evaluation, in particular "advantage" of having infinite lists, there task infinite lists make easy, or task possible infinite lists?

here's utterly trivial day-to-day useful example of infinite lists come in handy: when have list of items want use initialize key-value-style data structure, starting consecutive keys. so, have list of strings , want put them intmap counting 0. without lazy infinite lists, you'd walk down input list, keeping running "next index" counter , building intmap go.

with infinite lazy lists, list takes role of running counter; use zip [0..] list of items assign indices, intmap.fromlist construct final result.

sure, it's same thing in both cases. having lazy infinite lists lets express concept more directly without having worry details length of input list or keeping track of counter.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
