Now there's double indirection to get to the data... and you
also forgot the necessary postblits and dtors to maintain the
reference count. (these could be inlined or elided in some
cases, but not all)
You can't put the rc at the beginning of the pointer either,
since then a = a[1..$] won't work. So the added pointer is
unavoidable, your way or my way, both have a cost.
Hm, you're right. Would have been nice if the nice syntax could
be retained, instead of further unsightly library solution.
