Trait Normalizeable 

pub trait Normalizeable {
    // Required method
    fn can_normalize(&self) -> bool;
}

The Normalizeable trait defines a method to determine whether a node can be normalized.

Normalization is the process of converting a node into a canonical form that can be used to compare nodes for equality. This is useful in optimizations like Common Subexpression Elimination (CSE), where semantically equivalent nodes (e.g., a + b and b + a) should be treated as equal.
