Emacs doesn't like evaluating elisp code that starts with a shebang line.
Could we treat them as comments?

What do you mean by "doesn't like", exactly?

cat foo.el:

#!/foo
(message "hi")

emacs -Q -l ./foo.el

works fine.

Calling emacs script mode works fine on the command line, but the various
hotkeys for evaluating the same code from a buffer result in errors when
they encounter shebangs.

Please give a complete recipe starting from emacs -Q.

He's talking about the fact that emacs-lisp-mode does not know about the
#! magic, so M-x eval-buffer RET will throw errors when trying to
evaluate "#!/usr/bin/emacs --script".

Not for me, it doesn't.

    Stefan describes the error I experience. I use an assortment of computers
    and OS's, some throw this error and some do not.

    Emacs 24.2 for Windows does not throw an error (yay!)

    Emacs 24.x.y via Homebrew may throw this error (boo!)

Where x = ?
Where "may throw" means what? It sometimes does and sometimes doesn't?

Please give the full details, otherwise this is going to go nowhere.

If someone with Mac OS X could check that in 24.3, M-x eval-buffer on a
buffer with contents:

-------------
#!/bin/foo

(message "hi")
-------------

works fine like it does on GNU/Linux, I'll close this.

Hello.

It works fine on OSX, with 24.3.

No details, not reproducible.
