@ashwani99 awesome - this reproduces #1784 perfectly. I'll see what I can do to fix that.

My two cents, I think this should be done for every version of python supported

[chayim]

@WisdomPill Now that we have this, I think it's fair. @ashwani99 mind trying to yank the python-version and add it to your matrix, in addition to updating the name for this test to reflect the matrix? Then, I think we have something amazing, test-wise. Also, if you prefer I can add this change directly to your PR. I'd never want to step on your toes.

[ashwani99]

@chayim sure, I will add the support for all python versions 3.6+

[chayim]

@ashwani99 For what it's worth, this was alerady useful. I used it to validate #1792 our collaboration on the resulting change from #1784

Thanks @ashwani99! It has been such a pleasure. Merging as discussed in #1784
