 If a `limit` is provided, split the subject no more than the given number of times.
 Example: `foo::bar::baz::ban` -> `split :: 2` -> `[foo, bar, baz::ban]`

+#### `table <csv|tsv|json>`
+Destructure the current subject into a table from the given format.
+If `json`, assumes the data is a list of keyed objects (`{[string]: string|number|boolean}[]`).
+
 #### `join [<on>]`
 Join the current destructured subject back together using the given delimiter.
 If no delimiter is provided, it will preserve the existing delimiters between substrings.
