:keyword:`!for` or :keyword:`!async for` clause following the leading
expression, may contain additional :keyword:`!for` or :keyword:`!async for`
clauses, and may also use :keyword:`await` expressions.
If a comprehension contains either :keyword:`!async for` clauses or
:keyword:`!await` expressions or other asynchronous comprehensions it is called
an :dfn:`asynchronous comprehension`. An asynchronous comprehension may
suspend the execution of the coroutine function in which it appears.

If a comprehension contains :keyword:`!async for` clauses, or if it contains
:keyword:`!await` expressions or other asynchronous comprehensions anywhere except
the iterable expression in the leftmost :keyword:`!for` clause, it is called an
:dfn:`asynchronous comprehension`. An asynchronous comprehension may suspend the
execution of the coroutine function in which it appears.
See also :pep:`530`.
