For the sake of argument, can you construct a non-block-scoped `if (…)
…` which is actually any useful, assuming your mental model of
if (…) … <==> if (…) { … }
(which must be removed from teaching material) applies?
By the way, even in the current specification of let, we can still
construct a useless let:
for (let x = 42;false;) console.log(x);
(which is the same as the example you gave, using "if").
