class Prism::BlockParameterNode
Represents a block parameter of a method, block, or lambda definition.
def a(&b)
^^
end Attributes
The name of the block parameter.

def ===(other)
other.is_a?(BlockParameterNode) &&
(flags === other.flags) &&
(name === other.name) &&
(name_loc.nil? == other.name_loc.nil?) &&
(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.
