From: "Albert L. Wagner" Date: 2001-08-24T23:24:58+09:00 Subject: [ruby-talk:20289] Why doesn't Ruby have this... Over the last 30 years I have written production code in a dozen different languages. To me each language was the manifestation of a different paradidgm, a different mindset, a different model. I therefore developed a personal abstraction method that allowed me to say, "OK, I know what needs to be done. Now, how do I do that with THIS tool?" Perhaps, because this all took place before the internet, grunt programmers simply did not have access to the language developers. So that, not once did it occur to me to say, "What a stupid way to write a language. It implements functionality A differently than language X. It must be a bug or a design flaw." Yet, today, I see this phenomenon on every language ML and NG on the web. It is totally baffling to me. A Metaphor: A young carpenter went to work for a progressive builder. The carpenter had learned classical carpentry in his previous experience. He loved the feel of a newly sharpened hand saw, the heft and balance of a good hammer. But his new employer had acquired some new fangled contraptions: power saws and nail guns. When confronted with the nail gun his reaction was: "What a stupid looking hammer. Who designed this piece of crap? But, persisting, he placed a nail between his thumb and index finger placed the point where he wanted it. With great effort he swung the gun high and then down, crushing his fingers and firing half a dozen nails through his hand. According to the Buddha, expectations are the root of all evil. I really know of no other field of endeavor where so many "professionals" carry so much baggage of expectations into a totally new place. Who here has an explanation for this plague of rigidity? -- "It requires wisdom to understand wisdom: the music is nothing if the audience is deaf." - Walter Lippman
