initialise variable which would otherwise be unavailable in this scope

[juliankrispel]

So I'm not sure why this worked before (maybe because of an outdated lib-sass) but I'm getting a reference error if I don't do this, and that's correct behaviour. In Sass, blocks have their own scope so if you write

@if true == true {
  $foo: 'bar';
}

@debug($foo);

an error will get thrown because $foo won't exist in the same scope.
