@mansenfranzen I'm assuming you are/were here at the EuroPython sprints and submitted the CLA form already, yes?

In any case, the code in the change matches what was provided on the issue tracker by someone who definitely has submitted it, which is why I merged already.

[mansenfranzen]

Yes, filled in the CLA form already.
