Never use vars in a data class. Only val. With immutable objects a shallow copy is equivalent to a deep copy!

[itnoles]

also, var = reassigned

Additionally, the hashCode of an object changing while it's currently a key in a table somewhere is not a recipe for a fun time

Thanks you all! Do you have any solution for deepcopy with Data Class or normal Class ?
