     """ The cache data structure
 
     The data is stored as key value pairs of the following form:
-    (function, cache_tuple) -> (code, priority_tag, preamble)
+    (function, cache_tuple) -> (content, priority_tag, preamble)
 
     The parameters are:
     function : the function that generates the preamble code snippet
     cache_tuple : A frozen (sub)set of arguments to the function.
                   The map from function arguments to cache tuple controls
                   the amount of caching.
-    code : The code snippet to generate. No assumptions made.
+    content : The content to store. No assumptions made.
     priority_tag : Will later decide the ordering of the preambles.
     preamble : A bool whether this cache entry does generate a loopy preamble.
                This is usually not the case, when you generate something
