Escapes in interpolations

In Scala 2 there is no straightforward way to represent a single quote character " in a single quoted interpolation. A \ character can't be used for that because interpolators themselves decide how to handle escaping, so the parser doesn't know whether the " character should be escaped or used as a terminator.

In Scala 3, we can use the $ meta character of interpolations to escape a " character. Example:

val inventor = "Thomas Edison"
  val interpolation = s"as $inventor said: $"The three great essentials to achieve anything worth while are: Hard work, Stick-to-itiveness, and Common sense.$""
