Well, if it's deemed that it's not a big difference, then I don't think that I 
really have a problem with it. It bugs me a bit still, but that doesn't mean 
that it's a bad idea. We definitely need std.algorithm to generally be efficient, 
but we also need it to be useable. So, if the cost in efficiency is small enough, 
and there really are a lot of ranges that have this problem, then Slicer 
probably should be used.
