If I'm understanding you correctly, the kind of list you're talking about would be a value, and yes, you'd store it in an entity like an array or a hash.
First version.. an anonymous thingy is an entity, and the reference is the value of that entity. An anonymous entity has no bindings until we create one for it.
In practical terms, we have raw symbols, things that live in the storage heap, entries in a symbol table, and strings that we use in our code. The things in the storage heap encapsulate raw symbols, and the entries in the symbol table give us programmatic access to things in the heap.
The raw symbol is a value. We probably associate it with some human assumption, but it doesn't exist in the computer until we encapsulate it with an entity.
The thing in the heap is an entity. It encapsulates a value, which puts the symbol into the computer.
The entry in the symbol table is a binding. It gives us the power to access an entity whenever and wherever we want (subject to the scope limits of the binding itself).
The string we use in our code is the identifier. It's one field of the symbol table entry, and it's the thing we actually see when we look at a piece of code and think, "variable."
