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. +
