Uh, saying "retrying is fundamentally a looping operation" is not a
code smell. How do you plan to implement retry if not as a looping
construct under the hood? No matter how many times you assert
otherwise, "go back to this earlier point in the code and resume
execution from there" is pretty much the *definition* of a loop.
