Well, the requirement for save() being part of a forward range is fairly recent, and a bunch of ranges which are supposed to be forward ranges don't have them even though they're supposed to. The change was made fairly close to the release of 2.047, I believe, and it was missed for many ranges. It's mostly if not entirely fixed in svn. Actually, if I try and compile Bearophile's code on my machine (which has a fairly recent version of phobos), it compiles just fine. So, I don't know if array() should require an input range or a forward range, but the issue here has to do with recent changes to forward ranges which didn't make it into all forward ranges. It should be fixed with 2.048. - Jonathan M Davis
