> Is there an argument against using "not Enum.empty?(coll) and Enum.all?(coll)"
Nothing. When I came to this. I thought it would be good to having a function to return false when a list is empty and the probably the same implementation of all?/2, because in my personally case the all?/2 returning true for empty lists doesn’t worked. So, I searched on the Enum module to find this function and didn’t found nothing related. That’s why we’re here. Well, I’ll use this way from now on.
