            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.
