Description

With Python 3.6 some tests fail (several http.proxy.*), but overall Pulsar seems operable.
With Python 3.7 tests fail to even start:

SyntaxError: invalid syntax

Expected behaviour

At least the same level of functionality as with Python 3.6

Actual behaviour

I could pip install from PyPI in my Python 3.7 installation, but tests are failing, and the simplest examples fail with the same errors.

Steps to reproduce

Straightforward, see above.
