This is deprecated.

What you should be doing is using std.conv.emplace() with whatever 
allocator (say, malloc()) you wish to use.

Hi Alex,

Thanks for the answer.

As for the allocation, you mention malloc: is that malloc from the C 
runtime library? You also imply alternatives to this allocator; what would 
these be?

As for deletion, does on then invoke delete on the malloc'ed data pointer?

Pointing me to some example would be greatly appreciated.

Thanks.
- Adrian.
