# Prior to Python 3.7 'async' was an alias for 'ensure_future'.
# It became a keyword in 3.7.

# `gather()` actually returns a list with length equal to the number
# of tasks passed; however, Tuple is used similar to the annotation for
# zip() because typing does not support variadic type variables. See
# typing PR #1550 for discussion.
