Feature Request: Scala 2 & 3 Language Support

[ykhan21]

It would be nice to have Scala language support.
Scala 2 and 3 have different syntaxes. For example, Scala 3 has optional brackets and can be written as indent-based.
Scala 2 and 3 are both used in the wild because some newer versions of Scala brought binary incompatibilities with previous versions Scala.
