split - reverse - join $: join: ($: split:'0A:0B:0C:0D' ) reverse. convert hex address host/network. Btw, do we have a single message like split, but split at every nt element? 3 split '123456789' -> '123' '456' '789' > > > For Collection messages people is often interested in speed comparisons. > Because audience already knows how to do that in R, Python or other > language. > > Speed is not the subject of the article.
