+I'm reading up a little on byte-compilation in
+[GNU Emacs](http://www.gnu.org/software/emacs/) and I read about just
+exactly a feature that I needed.
+
+A while ago, I was working on my init<sup><a class="footref"
+name="fnr.1" href="#fn.1">1</a></sup> file, adding some
+`auto-complete` code since I wanted to try it again.  I
+noticed that, because `auto-complete` is installed through
+`package`, it couldn't load the appropriate files at
+compile time.
+
+I know that `package-initialize` should be called before calling or
+using any `package`-installed functions and I have it in my
+init<sup><a class="footref" name="fnr.1.2" href="#fn.1">1</a></sup>
+file, but this doesn't help at compile time.  So, ugly as I thought it
+was, I added
+
+[[!format el """
+(eval-when-compile (package-initialize))
+"""]]
+
+just above the call to the `auto-complete` functions.  I hated having
+to do that, I know it's just one line, but its not at all DRY<sup><a
+class="footref" name="fnr.2" href="#fn.2">2</a></sup>.
+
+Just now, though, I read about `eval-and-compile`, and according to
+the documentation in the elisp reference manual, it should do exactly
+what I want, eval both when running and when compiling.
+
+[[!format el """
+(eval-and-compile (package-initialize))
+"""]]
+
+I'm currently trying it out, I just tested it once and it seems to
+work like a charm.
+
+*Of course*, this might never have been an issue if I didn't use
+`emacs -Q` to compile my init<sup><a class="footref" name="fnr.1.3"
+href="#fn.1">1</a></sup> file, just to speed up loading during
+compilation a little bit.
