Type hints when unpacking a tuple?

Is it possible to use type hinting when unpacking a tuple? I want to do this, but it results in a SyntaxError:

from typing import Tuple

t: Tuple[int, int] = (1, 2)
a: int, b: int = t
#     ^ SyntaxError: invalid syntax

According to PEP-0526, you should annotate the types first, then do the unpacking

a: int
b: int
a, b = t
