I saw the introduction of the "programmer" on the dynamic language. The assault learned Scheme, the overall feeling is normal, the end is also good, the Polish style is good, it is just suitable for teaching, it can be very convenient to the algorithm and structure Description, the program that uses it can help understand the concept of algorithm and data structure. Looking at it with the purpose of learning, this is a classic language, but it is the only standard for the test truth. It's too unsuitable.
First of all, a large parentlet, readability is very poor; second, its writing style does not meet people's thinking habits, which will be deteriorated with its programming efficiency. In fact, I believe that the development direction of senior languages has always been developed towards the trend of natural language rules. It is the ultimate goal of reaching with computer with natural language. From this perspective, the Scheme is said to be a high-level language, it is a bit. It is said that it is just a toy of mathematicians. After understanding the Scheme, I found my own reason why I didn't like Emacs, and it was born to like it!
