# Records a slice of a copy of a's value (Signed.slice, narrow or select) as
# a Slice node with a's shape, the slice's shape with the axis kept and its
# plan. The value is checked first, so a refusal is the value's: an axis
# outside -rank..rank-1 is AxisOutOfBounds (13), a step of 0 StepNotPositive
# (19), a narrow past the extent or with a start before -extent, or a select
# index outside -extent..extent-1, OutOfRange (20), an unknown id
# UnknownNode; the tape comes back unchanged.
