Include Captures With String.split
The String.split/3 function comes with two options: trim and parts. However, when using it with a regex pattern, you gain access to a couple extra options, including include_captures. This is because when used with a regex pattern, String.split just invokes Regex.split which comes with extra options like include_captures.
Here is String.split in action by itself and with the supported trim option.
Adding in the include_captures option, we get a resulting list that includes the value captured by the splitting regex.
This isn't a documented feature, so it is only supported as long as Regex.split supports it and as long as String.split continues to delegate to Regex.split.
