I'm working with less for a while. I've used selector interpolation about 4 or 5 times, but I did not had the need to include nested classes over it until now.

So I've came across on what I think it could be a potential issue.
Here's a test case:

Input

@theGoodThings: ~".food, .beer, .sleep, .javascript";

@{theGoodThings} {
  &:after {
  font-weight: bold;
  }
}

Output

.food, .beer, .sleep, .javascript:after {
  font-weight: bold;
}

Output I was expecting:

.food:after, .beer:after, .sleep:after, .javascript:after {
  font-weight: bold;
}
