Serhiy, if I understand this, it _could_ pay big with even just a few operations. For example,
[0] * 1000000 + [1] + [2] + [3]
As-is, we'll copy the million zeroes three times. WIth the patch, more likely the original vector of a million zeroes would be extended in-place, three times with a single element each time.
But I don't know that people do that in real code. It would be great to find real examples in real could that would benefit. |
