Now that the compiler is completely in D, wouldn't it be a good 
idea to activate the GC in the compiler. I know that it requires 
some care for bootstrapping the compiler when there are 
dependencies to the D runtime, but the compiler would be an 
excellent example of the advantage of the GC (i.e. dumb fast 
allocations as long as there's memory, collection when no memory 
left which is miles away better than to get OOM-killed).
