The RExpression2 actor does not preserve the type of the elements in the
following R snippet:
list(1, "b", 3)
The token generated is:
{{"1.0"}, {"b"}, {"3.0"}}
Which is an Array of String Arrays rather than an array of mixed arrays.
We should preserve as much type information as possible when generating output
tokens
