          Represents the right-hand side of the operator. The type of the node depends on the expression.

          Anything that looks like a local variable name (including `_`) will result in a `LocalVariableTargetNode`.

              foo => a # This is equivalent to writing `a = foo`
                     ^

          Using an explicit `Array` or combining expressions with `,` will result in a `ArrayPatternNode`. This can be preceded by a constant.

              foo => [a]
                     ^^^

              foo => a, b

              foo => Bar[a, b]
                     ^^^^^^^^^

          If the array pattern contains at least two wildcard matches, a `FindPatternNode` is created instead.

              foo => *, 1, *a
                     ^^^^^

          Using an explicit `Hash` or a constant with square brackets and hash keys in the square brackets will result in a `HashPatternNode`.

              foo => { a: 1, b: }

              foo => Bar[a: 1, b:]

              foo => Bar[**]

          To use any variable that needs run time evaluation, pinning is required. This results in a `PinnedVariableNode`

              foo => ^a

          Similar, any expression can be used with pinning. This results in a `PinnedExpressionNode`.

              foo => ^(a + 1)

          Anything else will result in the regular node for that expression, for example a `ConstantReadNode`.
