Comment (?) breaks code

[Inviz]

section.left {
    background: orange !important;
}

//section.center:last[bottom] == section.left:last[bottom] !strong;

Can't be parsed. What's strange, making rule selector section.left:last works

[Inviz]

section.left {
    :first[top] == ^top !require;
}
section.right {
    :first[top] == ^top !require;
}
section.center:first[top] == section.left:first[top];

also doesnt parse for some reason

I had an issue where a comment broke things in #35.
