but here again, the differentiation is between when you want to return something / do something with the return value and perform only side effects

and at least in scala there used to be a convention that when you only want to perform side effects, the method was considered a "procedure" and put between

{}

- whether it was long or a one liner

so I wanted to know if there's something similar in Kotlin but it doesn't seem to be the case

even in Scala this convention seems to be outdated
