ways to declare function objects: lisp/python-style via closures or c#-style via delegates , respectively: bool find(t)(t[] haystack, bool delegate(t) needle_test) { foreach (straw; haystack) { if (needle_test(straw)) return true; } return false; } void main() { int[] haystack = [ , , , , , , ]; int needle
= ; bool needletest(int n) { return n == needle; } assert( find(haystack, &needletest) ); } the difference between a delegate and a closure in d is automatically and conservatively determined by the compiler. d also supports function literals, that allow a lambda-style definition: void main() { int[...
