Is it currently possible to call seq setLen without 0-initialization (for efficiency)? newSeqOfCap is not applicable since I want to reuse a buffer if not, should we add an overload for setLen?

If the new length doesn't grow past the current capacity it doesn't 0-init.

No way otherwise AFAIK.

It is not possible.

+1 on the feature. I also sometimes re-use buffers that would benefit from this.
