 ### Coding Conventions ###
 - The 'return' statement should only be used when it's control-flow properties
-  are required. Use a procedures implicit 'result' variable instead. Using the
-  implicit result variables allows both the Nimrod compiler and its various
-  backends to perform special optimizations
+  are required. Use a procedures implicit 'result' variable instead. This improves
+  readably.
+
+- Prefer to return `[]` and `""` instead of `nil`, or throw an exception if that
+  is appropriate.
+
+- Use a proc when possible, only using the more powerful facilities of macros,
+  templates, iterators, and converters when necessary.
 
 - Use the 'let' statement (not the var statement) when declaring variables
   that do not change within their scope. Using the let statement ensures that
