"Efficiency" is only meaningful in the context of a project's quantitative
timing requirements: an efficient implementation allows the project to meet
those requirements, while an inefficient implementation does not.
In the absence of such context, any claims of "inefficiency" (and especially
blanket claims such as "Unbounded_String is inefficient") simply demonstrate the
speaker's incompetence.
For an example of context, a decade ago I worked on a soft-real-time system that
made extensive use of Unbounded_String and had no problem meeting its timing
requirements. Unbounded_String was clearly efficient for that project. Since
most projects that would use Unbounded_String have even less restrictive timing
requirements than that system, it seems likely that Unbounded_String will be
efficient for them, too.
