How would you indicate to others that there are line breaks there at the end of each line?

What's that got to do with it?

You posted a blob of text. Blobs of text aren't arrays. Perhaps the blob of text is what the array elements consist of. But as presented, it's a blob of text. It could be just a single array element, each character could be an array element, or it maybe something in between.

@this_is_an_array = ("look, text", "fragments, each inside", "quotes",
+ ", and separated by commas");
