Throwing compile errors?

Hello guys,

we're trying to compile the following code, by using your library, but, for some reason it doesn't throw any errors.

This should be an integration of your library with our code, yet we can't seem to make it throw errors if the SASS code is invalid.

Could you please assist us?

We tested with this code:

$font-stack: Helvetica, sans-serif
$primary-color: #333

body
font: 100% $font-stack
color: $primary-color

nav
ul
margin: 0
padding: 0
list-style: none

li
display: inline-block

a
display: block
padding: 6px 12px
text-decoration: none

this should t
throw! ??@error {{{
