And the reason it is called "style" is that it is not essential to actually getting things done.
I likewise have written Common Lisp for decades. But I also get paid to do it, manage a team that does it, and see immense value in doing these extra things that hackers don't much care for, such as:
- making Lisp compatible with other languages through ABIs
- developing stylistic guidelines
- developing systems for static typing in Lisp to assist long-term development and maintenance of Lisp code
- etc.
So does style or the lack of any of the aforementioned bullets "block" the ability to "get things done"? Strictly speaking, no, but it inhibits outside interest in your project.
I concede that point. Also, I'm the only user of most or all of the Lisp I've written over the last 40 years.
Who has time for that these days, except for the very determined and dedicated?
I think Lisp is a superlative language with excellent tools—once learned. But it hasn't had its UI revolution from anybody who cares enough to do the work.
