Immutable?

21

Hey you might want to have a look to my project “imko” (immutable kotlin objects) which provides a cool way of defining immutable objects and a cool syntax for creating new versions of it:

Consider having a reference tree like

Object1
| \
|  \
|   Object2
|   |   \
|   |    \
|   |      Int2
|   Int1   
|
String

Creating a new verion with a different “int2” could look like

val version2 = 
object1{
        object2{
              int2{
                  times(2)
               }
        }
    }

Or

val version2 = object1{ object2{ int2{ times(2) } } }

I think this would be the equivalent in doing the same stuff with data-classes

val version2 = object1.copy(object2=object1.object2.copy(int2=object1.object2.int2.times(2)))

Let me know what you think about it :relaxed:
