Represents a find pattern in pattern matching.
foo in *bar, baz, *qux
^^^^^^^^^^^^^^^
foo in [*bar, baz, *qux]
^^^^^^^^^^^^^^^^^
foo in Foo(*bar, baz, *qux)
^^^^^^^^^^^^^^^^^^^^
foo => *bar, baz, *qux
^^^^^^^^^^^^^^^
Represents the optional constant preceding the pattern
foo in Foo(*bar, baz, *qux)
^^^
Represents the first wildcard node in the pattern.
foo in *bar, baz, *qux
^^^^
foo in Foo(*bar, baz, *qux)
^^^^
Represents the nodes in between the wildcards.
foo in *bar, baz, *qux
^^^
foo in Foo(*bar, baz, 1, *qux)
^^^^^^
Represents the second wildcard node in the pattern.
foo in *bar, baz, *qux
