I've been playing around with custom memory allocation schemes for some programs, which are based on regions. These work great, and are significantly faster for the use cases I'm using them for, than the general allocation scheme. However, everything would break if it were used with reference types and a moving GC because, as far as the GC knows, the regions I'm allocating from it are untyped.
What are the odds that some D implementation gets a moving GC in the foreseeable future? Are they significant enough that I should avoid relying on the GC being non-moving, or is worrying about such things just overdoing trying to be future-proof?
