 This trivial example shows some performance improvements that would be much more
 important should the allocation and construction/destruction of the objects be more 
 complex.
 
+In the case where the allocator is very fast (such as glibc's on Linux) this approach
+may not be necessary, but in the case of slow allocators (such as Windows' default), it
+could be interesting to consider such an approach.

 ## Safety
 AddressSanitizer, LeakSanitizer and ThreadSanitizer have been used to ensure the safety
 of the class. Tests have been added to ensure the correct behavior in all cases.
