Nim 1.4
There are a lot of gotchas with the new GC that make me nervous about this release:<p>> As far as we know, ARC works with the complete standard library except for the current implementation of async...<p>That's not a great endorsement...<p>> If your code uses cyclic data structures, or if you’re not sure if your code produces cycles, you need to use --gc:orc and not --gc:arc.<p>Seems like this is a big onus to put on the user -- it's tough to prove a negative like this.
