A refreshing break from Molt News. Now I want to check how vectors are implemented in my favorite languages.

[inhumantsar]

the `im` rust crate provides immutable data structures, one of them being an RRB-based Vec. don't remember what the stdlib Vec uses.

I believe Vec is a straight array underneath, which is reallocated at a larger size when full. And Vector in the `im` crate you mentioned looks very interesting indeed.
