Anyone asking for the addition of ARC or owning pointers to D, gets

I thought I made it clear that GC avoidance (which includes
considering built-in reference counting) is a major focus of 2014.

Sadly, although written as hyperbole, I feel that the above is fairly
close to the actual position of the ARC crowd.
I won't be surprised that half of current GC problems are because it's
simply too stupid as an allocator. I had some numbers that I'd need to
dig up were GC.malloc was ~2x slower then malloc even with garbage
collection disabled.
With that said I'd focus on ref-counting somehow coexisting with tracing
GC. It doesn't go well at the moment - try creating dynamic arrays of
std.stdio.File (that is ref-counted).
