What do you think of this ImmutableList class definition?

class ImmutableList<T>(list: List<T>) : List<T> by list.toList()

I don't think it's a given that

toList

will return you a new list

So maybe it's not immutable?

toList

will give you a new

ArrayList

@LeoColman good point, it depends on the implementation of

toList

. What about declaring it as:

class ImmutableList<T>(list: List<T>) : List<T> by ArrayList(list)

we miss the empty list and singletonlist optimizations from inside

toList

but that’s probably alright
