Containers library

One question for you /prog/!

Suppose you have a brand new language, which doesn't have any library yet. Which kind of basic containers / data structure would you expect?

>>33-34
I know. I program in CL as well. Nice job actually doing it though.

My point to >>29 is that it's possible to make nice built-in data structures which could not be implemented with operator overloading alone. Reader macros aren't mere operator overloading.

Therefore >>29 has obviously not read his SICP today and should crawl back to C++, along with his job.
