At the string literal level doesn't do anything, but the standard library adds an extension method to string called `stripMargin`. This has some nice examples https://www.oreilly.com/library/view/scala-cookbook/97814493...

The indentation is removed at compile time, per the JLS: https://docs.oracle.com/javase/specs/jls/se15/html/jls-3.htm...

> Incidental white space is removed, as if by execution of String.stripIndent on the characters resulting from step 1.

The new stripIndent() method is provided as a convenience to developers.
