This has been mentioned before. I was unable to find any information other
than the code itself which wasn't all that transparent to me. And the stack
allocate was soooooo simple. Is aligned_storage part of boost? Is it
documented anywhere? Is it part of any test suite? Has it been tested for
portability? In general I would prefer a boostified component over a
homebrew one. I'm really not sure of what the status of aligned_storage is.
Also, the nameitself didn't make it clear to me that its intended purpose
was identical to that implemented by stack_allocate.
