Resumen
Bugs happen because people create them when they can not remember the details needed to write correct programs. In this article, the author suggests the use of plentiful computer memory instead of wasting user's scarce biological memory. Programmers optimize inner loops of their source code because that is where the biggest performance gains are possible. The inner loop involves figuring out what to type and then typing it. It is required to create a programming environment that speeds both the figuring out and the typing. Getting correct all the details of source code demands lots of biological memory, frequently more than is available. But at any point in the typing of code, options are usually constrained by the legal constructs of the language, the functions and data available, and the context. Since the programmer's brain is already full of the details of the task and the algorithm, use of computer's brain is suggested. Emacs Menus is an adjunct to the Emacs text editor presenting the programmer with context-sensitive menus containing options that are least syntactically and typewise legal for the code under the mouse.
