I don't need yet another theoretical exercise in how to do computation in LISP, I need a concrete example of how to load and use getopts LISP code to construct command line programs in CCL (for example with CLON and CCL). Programs written in ANSI Common LISP which behave like every other program found in /usr/bin and /usr/sbin.
What LISP needs is more concrete examples solving everyday problems, like how to prop up a LISP web server? How to run LISP applications from one? How to perform string manipulation? Data extraction? How to connect to an Oracle database? SQLite database? How to package one's finished application into a pkgsrc or an RPM package? And so on, and so forth.
I'm over the concepts, but that doesn't mean I know how to solve everyday problems with the language, especially a programming language significantly different from any other programming language out there.
I spent countless hours trying to figure out how to get the shell program's getopts equivalent in LISP without writing my own getops implementation from scratch. No joy. The learning curve for writing a useful program is steep, and examples would give LISP adoption an enormous boost, like the Practical Common LISP book does (but it only solves one practical task throughout the entire book). Most people using a computer want to solve everyday tasks, so the examples should be task oriented, not to mention that dissecting the finished product is a great way to teach the language and the concepts, as well as doing things the LISP way. The link between UNIX and LISP knowledge is missing.
