Yep. Time ago I have read that the only science of "computer science" is in things like timing benchmarks and the like :-) > foreach (line; byLineDirect(stdin)) I don't like that byLineDirect() too much, it will become one of the most used in scripting-like programs, so it deserves to be short&easy. > write(r.head, ":"); Something tells me that such .head will become so common in D programs that my fingers will learn to write it while I sleep too :-) > r.next; .next is clear, nice, and short. Its only fault is that it doesn't sound much like something that has side effects... I presume it's not possible to improve this situation. >What the heck is going on? When does memory mapping actually help?< You are scanning the file linearly, and the memory window you use is probably very small. In such situation a memory mapping is probably not the best thing. A memory mapping is useful when you for example operate with random access on a wider sliding window on the file. Bye, bearophile
