Sequences are not immutable. A sequence is allowed to be consumed by
iterating over its generator. If the type you have is a sequence, you can
only assume that you can access the elements only once. For example, a
socket can be modeled as a sequence of bytes. Once the bytes are consumed
from the corresponding generator, they are gone from the sequence.
