Well, it is in the sense that it _is_ a deficiency of built-in
AAs for those
who want to be able to use different implementations for
different use cases,
but it's not something that can actually be fixed, and having
to use a library
solution isn't exactly all that bad anyway, especially when
most languages
don't have AAs built-in in the first place. It's just a
convenience feature.

Thanks for the dicussion! I thankfully haven't run into problems
with needed highly optimized assiociative arrays, but it's good
to know what the limitations are and why.
