I'd say the most common case one need a stack-allocated array is a 
temporary allocation which isn't going to survive end of scope. Even 
more in such cases for too large for stack data one want to allocate 
from thread local heap instead of shared one to prevent needless 
locking. `unstd.memory.allocation.tempAlloc` [1] will do the job. As the 
one of the most common subcases is a temporary C string creation
`unstd.c.string.tempCString` will help here.
