  <h2>Known failures</h2>
  <p>There are certain edge cases where Prism will fail.
  	There are always such cases in every regex-based syntax highlighter.
  	However, Prism dares to be open and honest about them.
  	If a failure is listed here, it doesn’t mean it will never be fixed. This is more of a “known bugs” list, just with a certain type of bug.
