Represents an array pattern in pattern matching.
foo in 1, 2 ^^^^^^^^^^^ foo in [1, 2] ^^^^^^^^^^^^^ foo in *bar ^^^^^^^^^^^ foo in Bar[] ^^^^^^^^^^^^ foo in Bar[1, 2, 3] ^^^^^^^^^^^^^^^^^^^
attr_reader constant: ConstantReadNode | ConstantPathNode | nil
Represents the required elements of the array pattern.
foo in [1, 2]
^ ^
Represents the rest element of the array pattern.
foo in *bar
^^^^
Represents the elements after the rest element of the array pattern.
foo in *bar, baz
^^^
