This is becoming unavoidable. This is really a pity, but the official Arc development is simply too slow (assuming it is moving, a quite optimistic assumption).
Integrating it into my forked Arc, but sadly something is interacting badly with the compiler and some macro is getting stuck in an infinite loop (which, if I don't catch with a ^C early enough, will force me to actually restart my computer T.T), probably from an incorrect compile. I'm debugging it currently >.<
Debugged! Now I just need to rewrite bits and pieces of arc.arc to clean it up and make it follow a more "axiomatic" path that will allow you to do neat things, like define how (+ (your-type 1 2) 42) will be (and adding hacks into ac.scm so that the axiomatic path isn't so slow).
