A compiled, number crunching dialect of Forth with a very good vocabulary (and the accompanying semantics) for n-dimensions matrix calculations sounds pretty neat. I’m surprised no one jumped in with a an APL reference, however there are some significant differences between an array processing language and a concatenative language with Fortran semantics.
Dr. Julian Noble (RIP) went down that road but realized it was overkill and switched to providing a "formula translator" for Forth. So it takes infix notation and translates it to RPN Forth code than is compiled interactively like normal Forth.
