Lisp is so powerful that problems which are technical issues in other programming languages are social issues in Lisp

Consider the case of Scheme, again. Since making Scheme object-oriented is so easy, many Scheme hackers have done so. More to the point, many individual Scheme hackers have done so. In the 1990s, this led to a veritable warehouse inventory list of object-oriented packages for the language. The Paradox of Choice, alone, guaranteed that none of them would become standard. Now that some Scheme implementations have their own object orientation facilities, it’s not so bad. Nevertheless, the fact that many of these packages were the work of lone individuals led to problems which Olin Shivers wrote about in documenting the Scheme Shell, scsh.

Programs written by individual hackers tend to follow the scratch-an-itch model. These programs will solve the problem that the hacker, himself, is having without necessarily handling related parts of the problem which would make the program more useful to others. Furthermore, the program is sure to work on that lone hacker’s own setup, but may not be portable to other Scheme implementations or to the same Scheme implementation on other platforms. Documentation may be lacking. Being essentially a project done in the hacker’s copious free time, the program is liable to suffer should real-life responsibilities intrude on the hacker. As Olin Shivers noted, this means that these one-man-band projects tend to solve eighty-percent of the problem.

Dr. Mark Tarver’s essay, The Bipolar Lisp Programmer, has an apt description of this phenomenon. He writes of these lone-wolf Lisp hackers and their

…inability to finish things off properly. The phrase ‘throw-away design’ is absolutely made for the BBM and it comes from the Lisp community. Lisp allows you to just chuck things off so easily, and it is easy to take this for granted. I saw this 10 years ago when looking for a GUI to my Lisp. No problem, there were 9 different offerings. The trouble was that none of the 9 were properly documented and none were bug free. Basically each person had implemented his own solution and it worked for him so that was fine. This is a BBM attitude; it works for me and I understand it. It is also the product of not needing or wanting anybody else’s help to do something.

Once again, consider the C programming language in that thought experiment. Due to the difficulty of making C object oriented, only two serious attempts at the problem have made any traction: C++ and Objective-C. Objective-C is most popular on the Macintosh, while C++ rules everywhere else. That means that, for a given platform, the question of which object-oriented extension of C to use has already been answered definitively. That means that the object-orientated facilities for those languages have been documented, that integrated development environments are aware of them, that code libraries are compatible with them, and so forth.
