Implicit cloning of types is evil. The first example with the mutable object is only surprising because the language decided to pass a copied struct by value instead of by reference.

But isn't that pretty much the distinction between value and reference types?

thats where my comment stems from: reference or value expextations are core to a language's behavior, if those cant be relied upon....

[pizzaknife]

thats a language efficacy/quality problem, not a type problem imho
