This emits a deprecation warning for `$a -$b` and `$a +$b`, since these look like they could be unary operations but they're actually parsed as binary operations. Either explicitly write `$a - $b` or `$a (-$b)`. See https://sass-lang.com/d/strict-unary for more details. This deprecation is only implemented for the new parser ported from dart-sass, not for the legacy parser.
