+** Pretty symbols
+Prettify symbols mode allows for users to declare 'symbols' that
+replace text within certain modes. For example, you may replace the
+'for' word in c-mode in trade of '∀'. Though this may seem like
+useless eye candy, it actually increases my speed of recognition
+(recognising symbols is easier than words for many, including
+me).
+
+Now here I provide a macro +pretty/set-alist. This macro works pretty
+simply: given a mode hook, as well as a list of pairs typed (text to
+substitute, symbol to replace with). Then I add a hook to the given
+mode, setting the prettify-symbols-alist to the symbols given.
+
+I've declared it pretty high up into my config so that the rest of my
+packages can leverage it.

+      ',mode

+Here's a collection of symbols I have currently that may be used
+later.
