run! function that raises error

[norpan]

How about having a additional run! function that raises an error instead of returning {:error, ...}?
This seems to be the canonical elixir way to do things and would make it easier to write code and not have to pattern match :ok on each call.

This might not be the solution you want (and this is an amazingly-late response), but you could write a bangify function (used like this).

Indeed one could write such a function, but Elixir itself has different versions of functions so it makes sense to supply these in this library as well. Otherwise every user has to research and implement these themselves.
