Declarative Object Graph Definition | Builders

[Suminda Dharmasena]

One area Scala can perhaps improve is declarative Object Graph Definition by extending the the syntax a bit. E.g. https://ceylon-lang.org/documentation/1.3/introduction/#declarative_syntax_for_treelike_structures, groovy builder

All major alternatives have it. Scala it is a bit more awkward than other languages JVM languages. Maybe Dotty can improve the syntax where this can be supported.

It seems to me that Scala can already do today what this Ceylon example shows, without any particular new syntax. Or am I missing something?

This can be done in Scala but the syntactic sugar around this is the most limited compared to other languages. ScalaTags vs Groovy MarkupBuilder, Ceylon HTML, Kotlin HTML.

Since XML support is going to be dropped and and the other languages have better markup encoding schemes there is a opportunity to improve the syntactic sugar.
