Variable is by definition mutable.

Constant is by definition immutable.

Why can't people get it through their heads in 2025? (I'm looking at you, Rust)

What about the result of a computation within a giant algorithm that I decided to name, and don't plan on rewriting it anymore?

That's surely not a constant like PI, is it?
