各种语言lambda闭包

swift

reversed = sorted(names, { (s1: String, s2: String) -> Bool in return s1 > s2 })

java8

list.sort((a, b) -> { Integer.compare(a.length(),b.length() });

C++

sort(x,x + N,[](float a, float b) { return std::abs(a) < std::abs(b); });

javascript

list.sort(function b(a, b){ a < b });

其他非主流语言

Float max = measurements.fold(0.0) ((max, num) => num>max then num else max);

var longStrings = lstOfStrings.where( \ s -> s.length > 2 )

Collections.sort(someStrings) [ a, b | a.length - b.length ]

max(strings, {a, b -> a.length < b.length})

list.sort |a, b| { a < b }
