Hi Pedro, Thanks for the proposal.
My counter-argument here is this: while this is useful for data science, how common is it to do data-science stuff with just Elixir's standard library? I’d imagine that most times, you'd be using a data-science focused library anyways. In that case, maybe this function belongs in there. Another similar argument is that this could be in a library instead of the standard library. Are there any particular reasons why this would belong in the standard library?
