It won’t be noticeable against a call to SecRandom, as noted, but there are
other circumstances where it’s a big performance hit to put a temporary buffer
on the heap. (Right now I’m working on some rather performance-sensitive
database code in C++ where avoiding a few heap allocations per iteration has
proven to be a big win.)
Does Swift have any solution for allocating stack-based array buffers?
