All one-dimensional arrays (arrays of rank one) are vectors. All vectors are sequences.
If a vector has a fill-pointer, then only its active elements (those before the fill-pointer) are considered part of the sequence.

All vectors with an element-type of character (or one of its subtypes) are strings.

See also integers as bits.
All vectors with an element-type of bit are bit-vectors, which is one of the standard specialized array types.
Functions that accept bit-vectors typically also accept bit-arrays, though those are not a specialized array type. (Actually that's not true. Fixme...)

Each association is a cons whose car is the key and whose cdr is the value.
