Blocks in Rebol are not a mere "stuff" delineated by square brackets. Rather, it's a heterogeneous container that can hold first-class values and represent both code and data (homoiconic property), thus serving as a base for the syntactically-rich data format. It also has a well-defined model [1] within the language, and, as such, can be freely operated upon at the run-time. On a grand scale of language design, blocks form a concrete-syntax tree that can be derived from (or converted to) both textual [2] and serialized binary [3] forms. Moreso, Rebol's syntax was in fact inspired by Logo. So, the relation between Arturo and Rebol seems to be very superficial; reminds me of Spry [4] that claims to be Rebol-like but is in fact an opinionated Smalltalk.

The basic premise (The friendly data format for human & machine) instantly reminded me of Red language [1], which, by the virtue of homoiconicity, is also its own data format (both textual and binary [2]) with 50 datatypes, many with several unique literal forms: date: 4-Oct-2020 4/11/20 time: 13:04:07 url: https://concise-encoding.org email: kstenerud@gmail.com ref: @kstenerud tag: <div color="red"> integer: 123 float: 123.45 1.#NaN -1.#INF pair: 67x89 percent: 9000% money: USD$0.50 binary: #{deadbeef} 2#{00101101} container: [#hashtag "string" %file.ext #(key value)] ...
