Represents reading a numbered reference to a capture in the previous match.
$1 ^^
The (1-indexed, from the left) number of the capture group. Numbered references that are too large result in this value being ‘0`.
$1 # number `1` $5432 # number `5432` $4294967296 # number `0`

@source = source

@location = location

end
Initialize a new NumberedReferenceReadNode node.

Return a symbol representation of this node type. See ‘Node::type`.

other.is_a?(NumberedReferenceReadNode) &&
(number === other.number)
end
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
