title: Rails REPL that is more than irb/pry but less than rails console
body: <p>I frequently want to try out small code snippets, often much smaller than classes, and even functions, just to make sure it works by itself so I don't need to test it by running a bunch of scripts, simply to fix small errors in a line of code or so.</p>
  
  <p>Besides irb/pry, I want to test Rails-specific code, such as <code>Object.blank?</code>. So with that, I want to have the Rails library loaded, but I don't need the full functionality that Rails console gives me. Especially when the application is not in a working state, the REPL will not open at all, and merely present a stack trace of the failure at hand.</p>
  
  <p>If anybody knew how to achieve this middle ground, maybe through the use of a particular gem path and <code>require</code> statement to load one of the other REPLs I have mentioned, could you illustrate those commands?</p>
  
  <p>I am working inside of a project using RVM to manage the gemset, and would like to not modify that environment at all, maybe only my general terminal environment, if possible.</p>
