A modern programming language that makes developers happier.

Generally I'd use `Language` annotation on a String literal for syntax highlighting and such, for example
```@Language("SQL")
val sql = "SELECT weight, name FROM boxes"```
But I'm reviewing code where parameters are annotated with it:
````fun doSomething(@Language("JSON") payload: String) { ...```
why would we want to do that? what does it buy us?

language injection at the call-site for literals,

i.e.
```doSomething("""{"this": "would automatically be highlighted as JSON"}""")```


And it's probably my PR you're reviewing :smile:

This annotation only affects IntelliJ IDEA inspections as far as I know. Is there a way to make it fail a Gradle build if you use invalid syntax?

Not that I'm aware of, no - you could possibly write an annotation processor that finds and validates them, but you wouldn't be able to validate dynamic strings like `"""{"my-key": "${value}"}"""`
