The alternative to REPL is a DEBUGGER with a great IDE. Don't get me wrong, REPL is nice, but IDEs are even better.

  A "debugger" is a REPL.

    It's a REPL with the ability to arbitrarily jump to chosen points in your application's execution, as opposed to attempting to populate the scope with copy-paste or dummy variables.
