Hello,
I would like to rewrite my fast linked list in Java [1] to C++ and
contribute it to STL. If we allow the operation
iterator at(size_t index) // runs in Theta(sqrt(N))
the data structure in question can add/remove an element also in total
Theta(sqrt(N)).
What do you think? Can it make it to the library?
Best regards,
rodde

Probably not.
Libstdc++ is an implementation of the ISO C++ standard library (and related
ISO C++ extensions).
We do have some historical extensions that are not part of the standard,
but they are a maintenance burden and we prefer to avoid adding any more.
We only include things that are in the C++ standard, or are proposed for
inclusion in a future standard.
