}

Flat stack-machine op for expression-local arithmetic/comparison.

Lowering folds constant subtrees to Expr::Literal and compiles dynamic arithmetic/comparison subtrees to post-order Vec<MathOp> so the runtime executes a single instruction loop instead of recursive Box walking. Call covers value-semantics functions only (INT, FLOAT, GLOB, LOAD_TOML, LOAD_JSON); INSPECT($var) uses Inspect to preserve the variable identifier (pre-evaluating to Value would lose the name).
