You are answering to a different issue than I was: Sure C and python are done
differently [your point]
I was saying that if Mikhail finds exceptions (and as he later explained 
classes) as a heavy-duty solution to a control-flow issue, he has a point

C++ has exceptions but no gc
Haskell has gc (like python) but no exceptions
So that suggests that while desirable, both are not in the bare-minimum set

My broader point (vive la Trump) was that if we learn to actively tolerate 
people with views wildly far from ours, the world would be a better place.

So what would I say to (people like) Mikhail?
"Here's the sources mate! Fork it! And cheers!"
