+** Auto completion

+
+   I'm not a great fan of any type of auto completion functionality in
+   programming. I think it's basically only good for getting really
+   long names in your file faster. I started programming in C#, in
+   Visual Studio, and they have their very powerful Intellisense
+   mechanism, which I used a lot. What I noticed though was that it
+   was keeping me from learning the APIs. Whenever I wrote some code,
+   all but the most basic and most-used calls I wrote from memory.
+   Many others were done after a few seconds of browsing through the
+   Intellisense pop-up.
+
+   Because of this, I disable the normal auto-complete pop-up.

+   #+NAME: auto-complete-dont-show
+   #+BEGIN_SRC emacs-lisp :tangle no
+     (setq ac-auto-show-menu nil)
+   #+END_SRC
+
+   On the rare occasion that I do call up the pop-up to see what the
+   completions I have available to me are, I don't want it to show the
+   quick help. The quick help usually shows up as a big extra pop-up
+   next to the completion list and it gets very messy when combined
+   with some other modes that add overlays to the buffer.

+
+   To keep the byte-compiler from complaining about undefined
+   variables, I only want this to be done after =auto-complete= is
+   loaded, not sooner.
