What I'd like for programming is a universal translator. Somebody writes a program in Java or Lisp, and I can read and modify it in Python and the author can read my changes in their own pet language. I write an Ant script and you can consume it with rubygems. You give me a program compiled into machine language or Java or .NET bytecode and I can read it in Python and run my modified version in the JVM, CLR, Mac, iPhone, Android, browser. Transparently, only looking at what the source language was if I get curious.
