`sass:dist` seems to be unhappy about ^^ 

```
Syntax error: Mixin transition-property takes 1 argument but 2 were passed.
        on line 39 of stylesheets/_panes.scss, in `transition-property'
        from line 39 of stylesheets/_panes.scss
        from line 4 of stylesheets/glazier.css.scss
```

Am I missing an updated or install?
