IMHO, a block in which the intention of a `finally: is not well understood,
needs refactoring.

Some *old* code is like that, but it doesn’t mean it’s *bad*.

Then, as a matter of personal preference, I’m not comfortable with that the
*defer* idiom talks first about things that should be done last. It’s a
debt acquired without enough syntactic evidence (Oh! Mi gosh!, There were
those defers at the start of the function I just changed).

Explicit is better than implicit.
