Nitpick, but Clojure's startup time isn't JVM startup time it's clojure.core startup time

This appears to be true, eg: cat Hello.java public class Hello { public static void main(String[] args) { System.out.println("Hello, world!"); }} eof javac Hello.java echo "Main-Class: Hello" > manifest.mf jar cvfm hello.jar manifest.mf Hello.class time java -jar hello.jar Hello, world! real 0m0.153s user 0m0.132s sys 0m0.020s vs: lein new hello cd hello # Pesty s-expressions, so hard to work with... ;-) cat src/hell…

And, for the record, with the same hello.scm, and guile (2.0.5 as found in Debian stable):

  # First run:
  time guile hello.scm 
  ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
  (...)
  Hello, world!

  real    0m0.066s
  user    0m0.044s
  sys     0m0.020s

  #Ed: with precompiled code under $HOME/.cache/guile (?)
  time guile hello.scm 
  Hello, world!

  real    0m0.040s
  user    0m0.036s
  sys     0m0.004s

Nah, because given I've never even tried most of the mature alternatives then it would be a faux pas to sell other people on why they should use it.

Perhaps. But even if it sucks: if it does at least one thing right, the other mature alternatives can learn another trick.

I'd wager scsh would provide a similar experience.

I'm starting to use SBCL for scripting, and on the system with a Lisp on an SSD drive the startup delay is unnoticeable. My friends tell me that on non-SSD setups, adding --script to startup options makes SBCL load almost instantly. It skips various initializations, disables debugger and REPL, and ignores shebang if it's the first line of a script, allowing you to write:

#!/usr/bin/sbcl --script

in your .lisp file.

IMHO the nicest Scheme for UNIX scripting is scsh. Its APIs are really well thought out and represent a lot of design work that hasn't ever been replicated by another Scheme (at least that I've seen). Some good examples of scsh scripting (some by the author, Olin Shivers) can be found at http://scsh.net/resources/scripts.html The manual is also very good: http://scsh.net/docu/html/man.html

The acknowledgements section made my morning, thanks.

Lisp on my Raspberry Pi is faster:

    pi@raspberrypi ~/lisp/ccl $ time ./armcl -n -Q -e '(progn (princ "hello") (quit))'
    hello

    real	0m0.112s
    user	0m0.020s
    sys	        0m0.080s
And the expression is first compiled to native code...

Have you released the source for it?

Nah, because given I've never even tried most of the mature alternatives then it would be a faux pas to sell other people on why they should use it.

Don't say it's better than the others then, just say "here's my version, what do you think of it ?".

You will always learn something by releasing it.

How does guile 2.0 do on that hardware?

I'm sure it's ironic, not pathologic. Otherwise i'd suggest to leave the Jack 'n Zak.

Just assuming that it's in good humor and not actually depressive would be another reason to feel ignored.
