String to integer tuple API

I have a related question.

(Well, I think it might be related; I’m a novice and everything’s possible. :smile: )

I see that Elixir’s naming conventions discuss the trailing-bang:

A trailing bang (exclamation mark) signifies a function or macro where failure cases raise an exception.

Many functions come in pairs, such as File.read/1 and File.read!/1 . File.read/1 will return a success or failure tuple, whereas File.read!/1 will return a plain value or else raise an exception…

So, in a parallel Elixir universe, could Integer.parse not exist and instead we’d have both String.to_integer and String.to_integer!?

EDIT: hmm, maybe that parallel universe would actually be a pain; I overlooked the fact that Integer.parse accounts for remainder_of_binary and String.to_integer doesn’t.
