a class contructor might be called only with certain attributes

[LGala]

given a class like

class LongClass(fieldNamingStrategy: FieldNamingStrategy, /*a lot more attributes between*/, excluder: String)

It's too verbose and error-prone to write a class constructor call like

longClass = LongClass(null, null, null, null, null, null, null, null, null, null, "hello")

It's way better to write a class constructor call like

longClass = LongClass(excluder = "hello")
