Represents assigning to a local variable in pattern matching.
foo => [bar => baz]
^^^^^^^^^^^^
Represents the value to capture.
foo => bar
^^^
Represents the target of the capture.
foo => bar ^^^

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