No, this is just a good old Forth programming language. It's a pity
that author of Joy even didn't mentioned Forth in his writings...

What differs from Forth is a presence of an attemt to describe
language in a mathematically-strict manner, more smarter base
primitives (syntax, scopes/hierarchies e.t.c.) and an
attempt of so called "Total RPN" in forthish world. RPN - reverse
polish notation.

SAJ> The system is very new and primitive, but looks promising.
Isn't new. Forth is 30-years old, unfortunately it didn't received
much interests from huge companies such as Microsoft or Borland.
