Talk:Immutable object

there is an error: ImmutableCart is immutable only if elements of the list are themselves immutable. Otheriwse, you copy the list allright, but you share the elements with the caller, so he can mutate them as he pleases.

I changed all references to vector in the C++ example to std::vector, as the C++ example would presumably be in a header file and it is generally considered bad style to include a global using namespace directive in a header file. I think it's very important for code examples to exhibit good style even if that makes them a little more verbose. - Zixyer 02:24, 19 December 2005 (UTC)
