90% of what a DSL would

Minus the readability

By overloading the methods in the builder, the example from the Readme could look like this :

val greeterClass = ClassName.get("", "Greeter")
val kotlinFile = KotlinFile.builder("", "HelloWorld") {
    addType("Greeter") {
        primaryConstructor() {
            addParameter("name", String::class)
        }
        addProperty("name", String::class) {
            initializer("name")
        }
        addFun("greet") {
            addStatement("println(%S)", "Hello, \$name")
        }
    }
    addFun("main") {
        addParameter("args", TypeName.get(Array<String>::class))
        addStatement("%T(args[0]).greet()", greeterClass)
    }
}

kotlinFile.writeTo(System.out)

which, i think, is much less "dense"

Of course, it would require to overloading the methods to match the builder of the parameter with something like this (in KotlinFile.kt):

fun addType(name: String, block: TypeSpec.Builder.() -> Unit) = addType(
        TypeSpec.classBuilder(name).apply(block).build())
