TODO:

• cartesian_unlist() should be modified to include names from named list elements
• move_me() should be modified to handle names with spaces, perhaps entered in a specific manner like either fenced with backticks like syntactically invalid names in R or << / >> or other fence.
• Riffle needs a byrow argument for row-wise interleaving of data.
