What's it worth to you?
I mentioned that I'm having a lot of fun with OCaml in Plan9. I'd like to do more (maybe try getting dune and opam to work), but the current version available is 4.07.
The reason is that there were significant changes to the build system after this point to facilitate more architecture support (arm - yay!), but those changes broke the things that made the Plan9 port simple.
I've offered a $100 bounty to anyone who can get OCaml 4.11 building in Plan9, but nobody seems interested. So, I've started down that road myself, but I'm enough of a Plan9 noob, still, that it's pretty challenging.
It's worth at least $100 to be. Maybe after banging my head against the wall for a while it will become worth more than that.
Time will tell.
