So, as it is quite obvious from the error message, SASS expects a fully qualified classname and .1 is not a valid class name since they need to start with alpha characters, not numbers.

SASS also cannot comprehend a couple of other more advanced scope selector operators (most notably grouping), but parses them correctly if preceeded with a backslash. As such, I will add a csscheme pre-processor that strips all backslashes from a selector (although valid in scope names and selectors, they aren't used anywhere).
