Thanks for responding. I had already seen the shebang script hack on the wiki, and although impressive I don't think it's a solution. It's shocking to me that someone who is into lisp would even think of getting rid of read macros though. For sure, there is a potential for abuse, but I don't think it actually happens much. The tone set forth by the built-in libraries will probably have more to do than anything with these types of policies. I've never experienced the pain from this, so maybe I'm just lucky and/or naive, but I always considered read macros one of the primary reasons that lisp is such a wonderful place to explore language ideas.
Anyways, I don't want to get into a debate for now. In the meantime how about defining #! to read through until the end of the line? Hell, it could even be restricted to the first line of the first file. This change shouldn't effect anything else, but it will make clojure programs as easily runnable as any other script, which should really be a must have for a new language on the scene. People coming to lisp, say from Ruby, Python or Pearl, already have to rewire their brains a bit, and making them substitute this garbage: #^:shebang '[ exec java -cp "$HOME/src/clj/clojure/clojure.jar" clojure.lang.Script "$0" -- "$@" for this: #!/usr/bin/env clj makes it seem like a big hack. For that matter, a standard clj script or executable should probably be a part of the package too. How about it? For the children. Oh, and if the read table is getting modified, I vote for Ruby like string evaluation too :-) Cheers, Jeff Stephen Gilardi wrote: > Clojure does not currently allow programs to define new reader macros.
