As it turns out, my profiling was a bit wrong.
But stills, the results are rather close.

On my data (the most typical range is about 6 elements) it is a little
SLOWER than string.format or concat version: 0.18 vs 0.16 for 1000
calls on range with 6 elements and 0.72 vs 0.62 on range with 100
elements.


Thanks to all for the discussion, I think I'd stick with string.format
version.
