Function component_wise_signed 

fn component_wise_signed<const N: usize, const M: usize>(
    eval: &mut ConstantEvaluator<'_>,
    span: Span,
    exprs: [Handle<Expression>; N],
    handler: fn(Signed<N>) -> Result<Signed<M>, ConstantEvaluatorError>,
) -> Result<Handle<Expression>, ConstantEvaluatorError>
where
    Signed<M>: Into<Expression>,

Attempts to evaluate multiple exprs as a combined Signed to pass to handler. If exprs are vectors of the same length, handler is called for each corresponding component of each vector.

handler’s output is registered as a new expression. If exprs are vectors of the same length, a new vector expression is registered, composed of each component emitted by handler.
