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.
