Hm,
((T*)malloc(1024*T.sizeof))[0..size];
works. Just needs careful initialization of each field, since they are
filled with trash ...
And you can even do slicing. Just don't append to them and keep track
of the initial reference ;)
You can append them. The append code will recognize that it's not a GC
block and reallocate.
Good to know.
I should also note, if you do this:
auto x = ((T*)malloc(1024*T.sizeof))[0..size];
x ~= T.init;
You have now lost the original reference to the data (because x now points
to the GC allocated block), so it will leak! So while appending does
work, you have to take care to still keep track of the original data. I'd
recommend something like this if it's a temporary:
auto x = (cast(T*)malloc(1024*T.sizeof))[0..size];
const origdata = x.ptr;
scope(exit) free(origdata);
