> In ‘stack-based languages’ the stack is, most usually, an explicit semantic construct which acts as the only available value for procedures to act on.

To the extent this is true, this is also true of all languages that anyone uses these days—C, JVM, Rust, Chez Scheme, GHC, python, ruby, ocaml, blah blah blah. The only difference is the syntax used to manipulate the stack. Acknowledging that syntax is the main difference from other languages seems key to evangelization. The idea of "implicit/explicit" doesn't really make sense. how do you refer to the stack in forth? You don't. How do you refer to the stack in C? You don't. Both operate with respect to the stack without ever referring to it via syntax. In both languages, the stack is invoked by referring to procedures/words.

Look if you want to keep up this fantasy that forth or factor is somehow more stack-oriented than any other languages, go right ahead. But you're going to fundamentally misunderstand why people use the language. It's the syntax! It was always about syntax. The stack is just a necessary implementation detail to deliver this syntax, same as in every other language that people actually use.
