+Lower-case, with underscores to separate words. Standalone functions do not need
+to be namespaced, but libraries can create namespaces by prefixing all functions
+with the library or package name, using `::` as the package delimiter.
+
+Note that certain circumstances, such as auto-completions in an interactive
+shell, do not work well with colon-delimited names, so avoid namespacing in
+those contexts.
+
Parentheses are required after the function name. The keyword `function` is
optional, but must be used consistently throughout a project.
-If you're writing single functions, use lowercase and separate words with
-underscore. If you're writing a package, separate package names with `::`.
-However, functions intended for interactive use may choose to avoid colons as it

Braces must be on the same line as the function name (as with other languages at
Google) and no space between the function name and the parenthesis.
