> I’d really prefer the option to determine when I’d like GC, as opposed to dodging the collector to avoid performance hits Fair enough. If SS14 used D maybe they wouldn't have these problems. D and early Rust (pre 0.2, like alpha alpha) had that. Problem is you split your community in two. You get a version of "What GC-color is your function/lib?". It's a tradeoff for some domains - allow no GC bypass you're going to run into nigh insurmountable performance cliff. Allow GC as opt-in and you run into issue of splitting your APIs in two.
