	// since there can be lot more things (var, @ directive, nesting..)
	// a selector must start at the end of a property or after a brace (end of other rules or nesting)
	// it can contain some characters that aren't used for defining rules or end of selector, & (parent selector), or interpolated variable
	// the end of a selector is found when there is no rules in it ( {} or {\s}) or if there is a property (because an interpolated var
	// can "pass" as a selector- e.g: proper#{$erty})
