This could be quite useful! On the other side it would be useful to add
functions like these as well:
def ok!({:ok, value}), do: value
def ok?({:ok, _value}), do: true
def ok?(_), do: false
And so forth for error as well. They are not really useful on their own
because matching is better, but for use in pipes that would be quite useful
(right now I use the exceptional library, which does similar things and
more).
