`Sequences`:idx: are similar to arrays but of dynamic length which may change
during runtime (like strings). A sequence ``S`` is always indexed by integers
from 0 to ``len(S)-1`` and its bounds are checked. Sequences can be
constructed by the array constructor ``[]`` in conjunction with the array to
sequence operator ``@``. Another way to allocate space for a sequence is to
call the built-in ``newSeq`` procedure.
during runtime (like strings). Sequences are implemented as growable arrays,
allocating pieces of memory as items are added. A sequence ``S`` is always

A sequence may be passed to a parameter that is of type *open array*.
