[pypy-dev] Adding support for PEP526: variable annotations

[Tin Tvrtković]

Hi Armin,

thanks for the tip. I actually need the annotations in runtime to do
serialization / deserialization (using two my libraries, cattrs and another
one for which I haven't written the docs yet). I use annotated attrs
classes. Usually I just move the type annotations from the annotation
syntax to "attr.ib(type=...)" using sed so it's not that big of a deal, but
it's still a chore.

Cheers :)
