        super(<<~ERROR)
          prism was unable to compile the pattern you provided into a usable
          expression. It failed on to understand the node represented by:

          #{repr}

          Note that not all syntax supported by Ruby's pattern matching syntax
          is also supported by prism's patterns. If you're using some syntax
          that you believe should be supported, please open an issue on
          GitHub at https://github.com/ruby/prism/issues/new.
