@at-root scoping

[meefox]

When you define functions in mixin.scss and wrapped it by @at-root rule.
Like:

@at-root {
  	@import 'mixin.scss';
}

// functions from mixin.scss will not be available here

Is it right behavior?

Being able to write an @import within an @at-root is pretty weird, but otherwise this is intended. Mixins and functions are lexically scoped: they're only visible within the enclosing brackets. This is as true for @at-root as it is for any other construct.
