I think our signals may be a little crossed.  What I had meant to tell Dave
was that an Emacs-shebang script is faster at starting up and printing "Hello,
world" than the equivalent ECL script -- which, for small little scripts,
means that using Emacs Lisp could be more efficient than using CL standalone
binaries.

I did not compare my test with Bash, however, or with using more complex
scripts, where I'd expect CL's native-language compilation to far outdo Emacs
Lisp.
