I'd use references to normal arrays and if I wanted to be sure that
a program can rely on realloc() I'd consider a simple storage pool
using this OS function. (GNAT has System.Memory with ready made
bindings on some platforms.)

Then just call new Flex_Buffer(as needed). Possibly behind some
Container like interface (or Controlled and Reserve_Capacity in
Initialize).
