`apply`is like my initializedBy but sets the receiver to the item to which you are calling it on and returns that same item. (editing my intiailizedBy above which accepts income param)

val mapThing = ImmutableSettingsBuilder() apply { 
     put("default" to "value") 
     put("other" to "value") 
}.build()
