Hi. I'm the designer of this feature. The reason for this is so that we can potentially have fenced string blocks in the future. for example:
```c# var s = """xml <Book><title/></Book> """; ```
and the like. Thanks!
```c# var s = """xml <Book><title/></Book> """; ```
and the like. Thanks!
var s = xml"""<Book><title /></Book>""";
