If you're trying to make a program fast, you almost certainly don't want
to be using unbounded strings, or any other controlled types. At least
not in any time-critical parts.
Controlled types use a lot of memory, and are quite slow.
AdaCore is working on improving this situation, but controlled types
will always be somewhat heavy.
