I went with the easy solution of using the default argument (and consistent with other existing functions), but should I split the /1 and /2 arity implementations?
Or possibly:
Suggested change
| :file.read_file(IO.chardata_to_string(path), opts) | |
| case opts do | |
| [] -> :file.read_file(IO.chardata_to_string(path)) | |
| _ -> :file.read_file(IO.chardata_to_string(path), opts) | |
| end |

Erlang is already doing the change you propose, so I think this fine as is.
