Overview

Mini String IO [Private]

Acts like a StringIO with reduced API, but without having to require that class.

The original codebase emitted directly to $stderr, but now SyntaxError#detailed_message needs a string output. To accomplish that we kept the original print infrastructure in place and added this class to accumulate the print output into a string.
