Function declarations hide unreachable code

Unreachable 'var' after 'return'. on the following:

function main() {
  return 'Hello, World!';
  var foo = 'foo';
}

main();

but no error on this:

function main() {
  return 'Hello, World: ' + bar();

  function bar() {
    console.log(foo);
  }

  var foo = 'foo';
}

main();

This bug was recently reported in different terms, so I’m renaming this issue to make it easier for folks to find.

Oh, wow – this has been open for 3 years. Is it going to be as hard to fix now as then, or have refactors since 2015 made things easier?
