I think this has been one of the impediments to the commercial use of Lisp. The syntax of a language is sort of the ultimate style guide. You loop using the built-in loop construct. You do something for each element using the built-in foreach construct. But without even much built-in syntax, much less a universal style guide, every Lisp programmer creates his own favorite language. That's part of the joy of it for an individual project and part of the cost for a group project.
