4. Cambios en los operadores
¿Tanta bronca por los operadores?

To me, one of the most agonizing aspects of language design is coming up with a useful system of operators. To other language designers, this may seem like a silly thing to agonize over. After all, you can view all operators as mere syntactic sugar--operators are just funny looking function calls. Some languages make a feature of leveling all function calls into one syntax. As a result, the so-called functional languages tend to wear out your parenthesis keys, while OO languages tend to wear out your dot key.

But while your computer really likes it when everything looks the same, most people don't think like computers. People prefer different things to look different. They also prefer to have shortcuts for common tasks. (Even the mathematicians don't go for complete orthogonality. Many of the shortcuts we typically use for operators were, in fact, invented by mathematicians in the first place.)
