Represents a block argument using ‘&`.
bar(&args) ^^^^^^^^^^
The expression that is being passed as a block argument. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
foo(&args)
^^^^^

def initialize(source, node_id, location, flags, expression, operator_loc)
@source = source
@node_id = node_id
@location = location
@flags = flags
@expression = expression

end
Initialize a new BlockArgumentNode node.

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

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