Do something x number of times
(where x is an integer >= 0)
Is there a one-liner for this?
I found that Enum.times was deprecated back in in 2012:
https://github.com/elixir-lang/elixir/issues/619
But it seems that ranges aren’t a proper replacement, since they don’t work for the case where x == 0.

If you mean the specific case of 0..0, it can be dealt with like this
Enum.each(0..x, fn
0 -> :nothing
_ -> do_something()
end)
