-When calling functions, omit the parentheses on the final method call in a chain. For example:
+When calling functions, choose to omit or include parentheses in such a way that optimizes for readability. Keeping in mind that "readability" can be subjective, the following examples demonstrate cases where parentheses have been omitted or included in a manner that the community deems to be optimal:
 
 ```coffeescript
 baz 12
 
-foo(4).bar 8
+brush.ellipse x: 10, y: 20 # Braces can also be omitted or included for readability
+
+foo(4).bar(8)
+
+obj.value(10, 20) / obj.value(20, 10)
+
+print inspect value
+
+new Tag(new Value(a, b), new Arg(c))
 ```
 
 You will sometimes see parentheses used to group functions (instead of being used to group function parameters). Examples of using this style (hereafter referred to as the "function grouping style"):
