Anonymous function works, function capture does not

[dantswain]

In an Ash resource:

actions do
  update :update do
    # this works
    change fn a, b -> change_fn(a, b) end
    # this does not work
    change &change_fn/2
  end
end

...

defp change_fn(a, b) do
  ...
end

The function capture version causes a compile-time error:

(redacted stacktrace, let me know if anything doesn't make sense - it may have been a search/replace error)

This should be fixed in main.

Thanks for the report!
