|There's more than one way to do things|
...is equivalent to this:
Who knows how that works, but it does. It's a perl idiom you need to know.As for this:
The only variable name you could think of, $split, is the same name as the perl function split() ? Don't ever do that. If you can't think up 10 unique variable names, you cannot be a computer programmer. Also, your variable names need to be descriptive. "Hey, Joe! I've got an array ref named '$split'. Guess what's in the array? Joe: Gold coins?"
Avoid writing $_ in your code. I suggest you read "Learning Perl 6th ed.". You need to learn modern perl.
