# Length is more complicated and less efficient in async mode. The
# reason for this is that we cannot know if length will be used
# upfront but because length is a property we cannot lazily execute it
# later. This means that we need to buffer it up and measure :(

# We however only do this for actual iterators, not for async
# iterators as blocking here does not seem like the best idea in the
