make-sequence

(make-sequence result-type size &key initial-element)

Creates a sequence of the given type and size. The result type must be a literal quoted specifier: a string type (string, simple-string, base-string, simple-base-string) builds a string like make-string, list builds a list like make-list, and a vector type (vector, simple-vector) builds an array like make-array. A non-literal result type is an error, and the keyword arguments are forwarded to the underlying constructor (so :initial-element follows its support there).
