Just wrote this to load the configuration files from
.emacs.
Did spend some (pleasant) time getting the output of
the shell (zsh) command "ls" into the variable `files'
(check it out).
Perhaps that is yet another thing to add for everyone
to use from the holster?
I agree silly configuration and cool hacks shouldn't be
added (unless they are really cool) but such basic
building blocks are great. It boosts creativity if
people don't have to get stuck on details all the time
when they want to do creative stuff.
(let ((files (with-temp-buffer
(call-process-shell-command
"ls ~/.emacs.d/emacs-init/**/*.elc ~/.emacs-no-bc"
nil ; no INFILE
t) ; BUFFER (t = current buffer, i.e. the temp one)
(buffer-substring (point-min) (point-max)) )))
(dolist (f (split-string files)) (load-file f)) )

No need to add it, see below.

Emacs has the shell-command-to-string function to do this. No need to
roll your own.
We also have the find-lisp package that can recursively traverse
directories, so no need to employ zsh-specific features.

If you have filenames with spaces in them, this will fail.

Of course I don't have that.
