Summary: Version of take() which takes from the back of a range Product: D Version: D2 Platform: Other OS/Version: Linux Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: jmdavisp...@gmail.com --- Comment #0 from Jonathan M Davis <jmdavisp...@gmail.com> 2010-07-21 16:41:01 PDT --- Most of the functions that we have in phobos at this point seem to deal with the front of a range rather than the back. Naturally, for a lot of stuff, that's exactly what you want, and there _are_ ranges which don't have a back, but for some functions, it would be nice to have a corresponding function which acts on the back of a range. The one which immediately comes to mind is take(). There's no way to take the back n elements of a range. There are ways to get more or less the same thing - you can copy the range and then pop off elements from the front - but there are situations where taking from the back of a range would be useful. So, I suggest that std.range have a function named takeBack() - or something similar - which does the same thing as take() except that it takes from the back of the range rather than the front. Now, there may be reasons which I haven't thought of why this wouldn't work very well (unlike take(), it obviously wouldn't work with infinite ranges), but I would think that it would be useful enough to at least look into adding it. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
