    That's subjective, Idk about "MUCH more difficult". All it does is moving the declaration to the correct visual scope, instead of a dangling up-front declaration. Admittedly, I understand most coders are aready trained to read the latter.

    The worst anti-pattern here is the catch- and finally-blocks living in a different scope. Really, who thought it was a good idea that finalization and error handling blocks must have no access to their subject scope? Every damn language copies that nonsense, except for js and its `var` hoisting.
