<li>To make it easy to create a Lexer, so you can focus on more complex problems.</li>
<li>To make the generated Lexer faster than anything you’d write by hand.</li>
</ul>
<p>To achieve those, <strong>Logos</strong>:</p>
<ul>
<li>Combines all token definitions into a single <ahref="https://en.wikipedia.org/wiki/Deterministic_finite_automaton">deterministic state machine</a>.</li>
