Sequences are collections storing elements under numeric index, in consecutive numeric range starting from 0. Those semantics are very much like those of CL:SEQUENCE.
To obtain value under index use the AT function. To modify content of the sequence use the following function.
RRB stands for "Relaxed Radix Trie". Elements are indexed using the successive 5 bit fragments of the index as the keys in the trees. This data structure is commonly seen in the new generation of functional languages (scala, clojure).
