The problem with immutable is probably due to this bug:

And casting to shared probably won't work due to this bug:

std.variant needs quite a bit of work done to it, and it's causing problems 
with std.concurrency is this case. In the interim, I suspect that just about 
the only way to get an AA across threads is to just make it shared and not use 
std.concurrency at all, as undesirable as that may be. Your serialization 
suggestion would probably be the only other choice, though that would require 
something like Orange, as Phobos doesn't have such facilities.
