! This file is needed very early in bootstrap.

! Sequences support the following protocol. Concrete examples
! are strings, string buffers, vectors, and arrays. Arrays are
! low level and not bounds-checked; they are in the
! kernel-internals vocabulary, so don't use them unless you have
! a good reason.

GENERIC: length ( sequence -- n )
GENERIC: set-length ( n sequence -- )
GENERIC: nth ( n sequence -- obj )
GENERIC: set-nth ( value n sequence -- obj )
GENERIC: >list ( seq -- list )
