* `(1 2 "three")` or `(list 1 2 "three")` - a list of values read from start to end (sequential access)
* `[1 2 "three"]` or `(list 1 2 "three")` - a vector of values with index (random access)
* `[1 2 "three"]` or `(vector 1 2 "three")` - a vector of values with index (random access)
* `{:key "value"}` or `(hash-map :key "value")` - a hash-map with zero or more key value pairs (associative relation)
* `#{1 2 "three"}` or `(set 1 2 "three")` - a unique set of values
