Re: std.allocator needs your help

[ponce]

Great news! It looks like a big improvement on akward C++ 
allocators.

(For what it's worth I have a working implementation of aligned 
malloc/free/realloc here 
https://github.com/p0nce/gfm/blob/master/gfm/core/memory.d, which 
can be the basis for an allocator layered upon another)
