Java is the best for other people to understand your abstractions…

• with the exception of poor data-structure initializers.
  • but you can get around this pretty easily by writing fclever initializers
• Excessive OOP considered hazardous
• Java's static typing provides an excellent source of computer-checked, always up-to-date documentation.

Lisp is the best for creating new abstractions quickly…

• but lack of static typing means its sometimes difficult to figure out how to properly call code, etc…
