Actually, it says it right there: keywords, numbers, and strings.
Admittedly, it doesn't say it's exhaustive (partly because this set
could be expanded in the future, tho at this point it seems unlikely).

Keywords can't be bound since their value is constant. Same for nil
and t. So that should be "obvious enough". As for _ I think it should
also be obvious enough that between a rule "for _" and rule for "SYMBOL"
the most specific rule should take precedence.
