I think that’s not true; vanilla OCaml is already a competitor to Go, etc. OxCaml is explicitly an effort to compete more with Rust (the “Ox” in the name is to evoke “oxidizing” = rusting)
Hah, I was reading it as `0x`, a common prefix indicating hexadecimal, though I can't say my brain made any leap as to why "0xCAML" would be any more hex than standard.
Examples, real time Java, Oberon, Pascal, BASIC Stamp, Propeller,..
