Most comment parsing uses lexical states to achieve this without clash
with other tokens (since the longest match wins).
So when you encounter the "/*" you switch to a new state, and in that
state there are only 2 tokens defined, "*/" to return you to the
previous lexical state and ~[] to eat any other characters
_one_at_a_time_ so that the endOfComment token is always matchable.
