this will give somewhat better performance because the ~= will allocate 
and copy a lot.

C[] copyinst;
copyinst.length = inst.length;
foreach(i,c; inst) copyinst[i] = c.dup;


if you want compact code and don't mind it being a bit confusing:

C[] copyinst = inst.dup;
foreach(inout i; inst) i = i.dup;
