 `scala.quoted` contains objects that can help extracting values from `Expr`.
 
 * `scala.quoted.Const`/`scala.quoted.Consts`: matches an expression of a literal value (or list of values) and returns the value (or list of values).

 These could be used in the following way to optimize any call to `sum` that has statically known values.
