Actually, I'm an old school OpenBSD user who still programs with ed(1). Check misc@ out back a number of years. I've had to move away because OpenBSD isn't the greatest platform for doing high performance GPU research. :-( The compiler is already portable to BSD. However, the underlying library I use to do GPU programming (ArrayFire) is not ported to BSD, though it Is for Linux. The Dyalog interpreter is available for AIX as well as Linux, and that's what you need to host the compiler right now. If Dyalog received the interest, it would be pretty straightforward to port Dyalog APL to BSD. If one wanted to provide a self-hosting Co-dfns compiler, you could implement a minimal dfns interpreter and then run the Co-dfns compiler over that. To my knowledge no such interpreter exists yet. However, porting either ArrayFire or the Co-dfns runtime would go a long way to doing this, because you could then share the runtime library between the interpreter and the compiler. So, yes, this is quite possible, and probably not even that much work. I'd welcome such a contribution. :-)
