+**** Condensed lists
+LaTeX is generally pretty good by default, but it's /really/ generous with how
+much space it puts between list items by default. I'm generally not a fan.
+
+Thankfully this is easy to correct with a small snippet:
+#+name: latex-condense-lists
+#+begin_src LaTeX
+\\let\\olditemize\\itemize
+\\renewcommand\\itemize{\\olditemize\\setlength{\\itemsep}{-2ex}}
+\\let\\oldenumerate\\enumerate
+\\renewcommand\\enumerate{\\oldenumerate\\setlength{\\itemsep}{-2ex}}
+\\let\\olddescription\\description
+\\renewcommand\\description{\\olddescription\\setlength{\\itemsep}{-2ex}}
+#+end_src
+
+Then we can just hook this in with our clever preamble.
+
+#+begin_src emacs-lisp :noweb no-export

 We could just use minted for syntax highlighting --- however, we can do better!
