Meta-level thinking

From Ola Bini:

I have been trying to figure out what characterizes some of the best programmers I know, or know about...

When people try to become better programmers there are generally a few different kinds of advices you can get. The ones that seem prevalent right now is (among others):

• Learn - and understand - Lisp
• More generally, learn a new language that is sufficiently different from your current knowledge
• Work with domain specific languages
• Understand metaprogramming
• Read up on the available data structures (Knuth anyone)?
• Implement a compiler and runtime system for a language
