# 2. Teach physical-expression utilities about `CastColumnExpr`
* **Goal:** Ensure all helper subsystems that reason about expressions
understand the new node before other components depend on it.
* **Scope & Location:** `datafusion/physical-expr-common`, `physical-expr`
optimizers/utilities, plus associated tests.
* **Key Tasks:**
* Extend equivalence tracking to treat `CastColumnExpr` similarly to other
projection expressions when comparing canonical forms.
* Update interval propagation / ordering analysis to either unwrap or
conservatively handle `CastColumnExpr`.
* Teach cast-unwrapping simplifications (`strip_aliases`,
`strip_nullability_casts`, etc.) to recognize when a `CastColumnExpr` can be
bypassed (or confirm it must stay).
* Add regression tests for each utility verifying expected behavior with
the new node.
* **Dependencies:** Builds on spec #1 (expression must exist).
* **Out of Scope:** Planner adapters and serialization changes.
