P.S. Maybe I should repost my question on SO? I really thought it was a bug, so I posted it here.
You could, but I'd say the same thing there - it is no bug, the algorithm legitimately needs that functionality to split successfully. At the same time, filter legitimately needs to /drop/ that functionality to work efficiently.
So the error kinda sucks (maybe i should write this as a tip, whenever you see that pattern, adding a .array can work around it), but it isn't a bug.
The reason splitter doesn't try to automatically buffer or something like that is that std.algorithm tries to be as low cost as possible in all cases, and asks you to be aware of and pay the cost when it needs to occur.
So if it needs a buffer and can't get one for free, it fails to compile, so you are aware of the problem and can provide one that works best for you (or just stick in .array somewhere to do an easy, generic solution)
