Instance Attribute Details

#value ⇒ Object (readonly)

The value to be splatted, if present. Will be missing when keyword rest argument forwarding is used.

Instance Method Details

#===(other) ⇒ Object

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
