Hello,

I was testing out my grid generator file in sassmeister with libsass 3.0.1 and I get Invalid property name errors. The line numbers seem way off where the problem is, maybe from loops, so I haven't had much luck reducing it down.

I know it doesn't like .#{$namespace}--1,

I haven't been able to test in 3.0.2, I'm not really sure how to do that.

Here's the whole thing, maybe it will have useful test cases in it:
