## Known failures

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.

### The global context is highlighted as a verb
