Almost, but not completely. They share implementation and much of observable behavior (and former can be used to initialize latter) but one is mutable run-time entity and other - compile-time (and thus, of course, constant). As they don't have proper representation in the type system, it makes them quite different.
I don't think it's correct or useful to label one as compile-time and the other as runtime. I think the mutability or immutability of the expression tuple is an obvious result of its lvalue-ish or rvalue-ish nature, respectively. As such - with the current semantics - I'm not sure it's important to be able to easily distinguish the two. I'd be happy to be convinced otherwise if you think it's important.
