The association :-)
Technically, there's some hash table in the background, where
the implementation can look up symbols and what's been "hung"

I'd say that the "maths" view was an inspiration, so it always helps
to keep it around for comparison. But it's important to remember that
there are differences.
That doesn't mean that maths can't model assignment, though.
