> A pointer stores a number I disagree with this, and I think it's important to understanding pointers. A pointer is a number. A variable stores a value.[1] A variable has an address, a value does not; a value might be stored at an address, but it doesn't intrinsically have an address. A person might live in a building, but the building has the address, not the person, who can move. [1] (In C-like languages this is true. In Python, a variable stores something you're largely not allowed to inspect, which might be a pointer to a data structure with data and metadata. Haskell has no variables, just names for constants.)
