def node_reparsed_with_modern_features(node)

Otherwise, we would get the unparsed node as `foo.[](bar)`.
"index sends" (i.e. `[]` calls) back to index accessors (i.e. as `foo[bar]``).
Modern features include "index send" emitting, which is necessary to unparse
This method exists to reparse the current node with modern features enabled. 
def node_reparsed_with_modern_features(node)
  # Create a new parser with a modern builder class instance
  parser = Parser::CurrentRuby.new(ModernBuilder.new)
  # Create a new source buffer with the node source
  buffer = Parser::Source::Buffer.new(processed_source.path, source: node.source)
  # Re-parse the buffer
  parser.parse(buffer)
