Represents reading a reference to a field in the previous match.
$' ^^
The name of the back-reference variable, including the leading ‘$`.

end
Initialize a new BackReferenceReadNode node.

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