LL grammar generated by some "ε"-free LL("k") grammar. As allowing more tokens of lookahead makes the parser strictly more powerful, the languages that can be recognized with a LL("k") parser are a strict subset of the languages that can be recognized by a LL("k+n"), "n > 0" parser. This creates a strictly increasing sequence of sets: LL(0) ⊊ LL(1) ⊊ LL(2) ⊊ …. Since these are all DCFLs, a corollary is that for any fixed "k", there are DCFLs that cannot be recognized by a LL("k") parser. An LL parser is called an LL(*) parser if it is not restricted to a
