Note that it only takes the "#([^\"]" spot. The "#c" convention is
completely untouched, unless "c" is "(".

Of course, I'm open to other variants, if this isn't accepted, maybe
"#l(foo bar)". The initial suggestion would be immediately familiar to
any Clojure programmer. Clojure is a bit more popular than Elisp,
judging by 8000 vs 3000 questions on Stack Overflow, and 25,000 vs
22,000 repositories on Github.

I'm also open to trying my hand at the "CL-style reader-macro
facility".  But this task would be much more complex than the simple
hack that I'm presenting here. So I really want to make sure that this
feature is wanted and will be accepted before I spend time on it.
